UK Systems - Draw Indicator

After posting the last blog post, I remembered there was one other piece of analysis I wanted to carry out this Summer. It is something I said I would have a look at after the season was done but being honest, with everything else on the go, it slipped my mind.

What I wanted to look at was the performance of the UK bets and comparing the performance of when they do/don’t appear on a draw algorithm. Of course, the limitation with this analysis is that I have 4 seasons of live results on some UK systems and only one season of live results for the UK Draw systems, so I don’t think we can draw too many conclusions. Having looked at the data, I think it is very confusing and therefore, it’s something we need to park until next Summer I think.

Before looking at the data, I guess I expected to see that results would improve for my systems if the same game didn’t appear on a Draw system. If a game is on a Draw system, it isn’t going to be as profitable as bets that don’t appear on Draw systems. That was my hypothesis but then again, given how profitable the Draw systems looked before they went live, it sort of follows that this would be the case. If the Draw systems had a 20% ROI, it must be the case that the results of the outright systems would be better if the Draw systems didn’t find the same bets!

Anyway, having done the analysis, I think last season is very confusing and doesn’t fit in with the historical results (which to be fair, isn’t totally surprising).  I think once we get a few seasons Draw data behind us, we can draw more meaningful conclusions.

Here are the results anyway:


For the first 3 seasons, it is clear that if the Draw systems don’t find the bets, it is better for the systems results. No surprise given the Draw systems had such high returns. However, last season, the opposite is true. An ROI of 6.2% overall where the bets appear on Draw systems and an ROI of only 1.5% where the bets don’t appear on Draw systems. Hence, rather than reducing stakes where the Draw systems found the same game, we should have been increasing stakes!

I think we need to wait until we get more Draw data and then we can maybe draw more meaningful conclusions.

I’m done with analysis for others.  Next task for me is to decide what I do myself next season! So many ideas, so many ways to play and only 2 weeks left until the first bets!.

Next post will hopefully be a guest blog post from a TFA subscriber. Keep an eye out for it……

Euro Underlying Results

One of the outstanding pieces of work I had this Summer was to pull together a tracking sheet to monitor the underlying results for the Euro leagues. I’d sort of been doing it in the background but it was only earlier this week that I got on top of the email exchanges with subscribers and given the fact my baby hasn’t arrived yet, I thought it was a good opportunity to complete this piece of work and do a quick blog post on it.

As you will remember, it was only last season that I started tracking the underlying results of the UK leagues closely. I’ve always been acutely aware of the fact that my system results are heavily influenced by what happens to the underlying results but I didn’t ever feel the need to pay too much attention as at the end of the day, I can’t change the underlying results. However, what I found last season was that without knowing exactly how the underlying results were behaving in the short-term, it was impossible to explain some of the variance I was seeing in the results on a monthly basis.  I set up a little tracking sheet to monitor the results on a monthly basis and it really helped me with the mental side when I was experiencing some of the ups and downs.

So, I’ve now completed the same piece of work for the Euro leagues.  

Being honest, I’d looked at something like this before in early 2010 before I built the first UK algorithms as back in the day, my intention was to build Euro ratings first rather than UK ratings. However, my first few attempts at building Euro ratings weren’t too successful as I couldn’t find a way to create an edge on Aways (looking at Draws hadn’t even been a consideration) and when I looked at the underlying results, I could understand why. Basically, from 2006/07 to 2009/10, backing all Homes blindly was pretty near break-even in these top 4 Euro leagues (Italy, France, Spain & Germany). Backing Aways was heavily loss making and therefore, trying to find an edge with Aways was very tough.

Anyway, roll forward 4 seasons and now I have two seasons proofed results behind me in the Euro leagues for Homes/Aways (not the greatest results but a foundation to build from) and next season will see the first season of Euro Draw bets. Therefore, it seems like it was worth investing the necessarily time to create something similar to what I have for the UK bets.  I have data going back to 2006/07 but similar to the UK underlying results, I’m going to concentrate on the last 4 seasons. The further back you go, the less competitive the prices are and therefore, the results look a bit different to the most recent years.

So, here’s the results for the last 4 seasons:

A really interesting picture and considering I’m about to embark on new Euro Draw systems, let’s just say my confidence is a little lower having seen these underlying results!

I think the first comment is the fact that if following Homes only, you should struggle to make a loss in these Euro leagues long-term based on these results. Many of my blog readers will be aware of other tipster services that specialise in Homes in Euro leagues and looking at the Underlying results, I can see why they have gone down this approach.  

Interestingly, in my first season of Euro ratings, my Home bets were terrible and therefore, I think this highlights how weak the ratings were I built. I knew that of course and that’s why I binned the ratings and started again with new Euro ratings last season. Also probably explains why I ended up with such a high % of Home bets on my rating algorithms now compared to what I had before. If you are relying on Aways in these leagues to make a profit, you will struggle I think long-term. 

Looking at Aways, it is a tough place to make money in these leagues and we’re looking at a loss of around 3.9% over the last 4 seasons.

However, compared to the Draws, a loss of 3.9% doesn’t look too bad! The Draws have lost 6.4% over the last 4 seasons, last season lost 8.5% and the 2010/11 season lost 10.5%. Not exactly an easy place to make money!

If I look at the month by month view, we see lots of months where backing all Homes is profitable and considering this is the first time I’ve really looked at this, I find it very interesting.


20 winning months from 37 if backing all Home bets. Amazing really but then again, given the overall results, shouldn’t be too surprised but it shows how consistent this method is.

12 winning months from 37 for Draw bets shows the difficulties playing in this space. Only 2 winning months in the last 12 shows how difficult it has been recently in these leagues if backing Draws.

16 winning months from 37 for Away bets and I was surprised it was as high as this given the issues Aways have generally.

Similar to what I do with the UK underlying results, I’ll be keeping tabs on these Euro results every month and when writing monthly reviews, I’ll try to use what I have seen to hopefully understand some of the performance issues we’re seeing on a monthly basis.

So, does the above change my thinking at all about the Euro Systems and Euro Draw Systems?

In terms of the Euro systems, I think last season was a pretty easy season for backing Homes/Aways and therefore, maybe I’m not too surprised that my Euro systems made a decent profit. I guess if I go back another season, it wasn’t that much more difficult and my ratings bombed badly, so I think that highlights deficiencies in my ratings for the first season which is what I concluded myself based on the poor performance.  I said at the end of last season that I still thought my Euro systems had a lot to prove and I think the above backs up my thinking. Let’s see how they do this season.

In terms of the Euro Draw systems, I think the above has opened my eyes to how tough this place is to make money. Being honest, having seen Cassini’s results over the last two seasons, I realised it wasn’t exactly an easy place to make a profit but I’m not sure I’ve seen too many tougher groups of data to try to find a betting angle over the last few years.

Last season, backing Draws in UK leagues was very tough with an ROI of -5%. This was the worst ROI since season 2007/08 for these leagues (also the lowest strike rate since then) and therefore, I was overly excited about how my Draw systems had outperformed the underlying return. For 3 of the last 4 seasons, the Euro Leagues have had a worse ROI than this!

Unless conditions get a bit easier for Draw backers (higher strike rate), I would struggle to believe that my ratings could make a profit next season. It’s not impossible (my UK Draw systems did it last season) but experience tells me that when the underlying results are tough, making a profit from a very high number of bets is just as tough. The odd system with lower turnover can do well but the higher turnover systems may struggle if the losses are as bad as 3 of the last 4 seasons. 

Of course, as I have pointed out before, tracking underlying results is great for explaining what has happened historically but in terms of explaining what may happen next, they are about as useful as a chocolate teapot. Some will say the Euro leagues are due more draws after the last few seasons whereas other will say that the trend has changed and the market hasn’t caught up and therefore, there is no value in draw bets in these leagues unless the strike rate increases.  Let’s see what happens this season!

FTL Systems - Season 2014/15

Well, the time has come to take the wraps off my FTL systems for the upcoming season.  I’m still three weeks away from my first bets as I wait until 6 games are played in each league before getting involved but now seems a good time to start outlining my assault on Cassini’s tipster league this season.

Firstly, before I discuss the plans for the upcoming season, it’s probably worth having a quick recap of the system I entered into the FTL last season and how it performed.  The official (prices on a Thursday evening) results of the system last season were a profit of 3.4pts from 401 bets for an ROI of 0.85%. A disappointing performance and ranking it in terms of my TFA systems last season, this unique system would have finished 36th out of 53 systems last season. Clearly, this was slightly frustrating as I obviously hoped that I would end up with a system in the FTL which was better than most of my other systems but this wasn’t to be.

The biggest issue I found last season was the fact that the odds used for P&L purposes in the FTL are Pinnacle’s odds on a Friday afternoon. I’ve done various bits of analysis myself on an ad-hoc basis and I’ve seen a very good analysis from a subscriber this Summer comparing Pinnacle prices over time for my bets and as I expected, Friday afternoon is a low point when it comes to the odds of my selections.  The odds start to rebound a little from Friday and by the time kick-off approaches, there are much better odds available than on a Friday. However, the best odds available are at the time I release the bets as you would expect.

Even though I understood the potential issues with the odds in the FTL, I didn’t really think the impact would be as big as it was last season. The official results in the FTL showed a loss of 10.72pts from 401 bets for an ROI of -2.67%. A 14.12pts swing across 129 winning bets. Given my average odds were 3.11, losing over 0.1pts per winner is a big swing (c. 5%) and ultimately, for football systems such are mine which are price sensitive, I think it shows the barriers my FTL system will have to overcome to do well in the FTL.

So, last season was a bit of a nightmare and at the end of the day, it cost me £125 in bounty prizes for other contestants who finished in front of my FTL system.  Given I’ve put up another bounty of £25 for everyone who finishes in front of me this season again, I’ll be trying my best to do better this season!

FTL Bounty System

One of my regrets from last season was not entering a TFA system into the league! I thought it was a good opportunity to try out a different system and test something live but it flopped badly. Therefore, lesson learnt and this season, my FTL bounty system will be one of my 61 live TFA systems this season.

Given what I learnt last season about the odds movements, I think I have to steer clear of my main systems this season which most people are going to be following. I would love to put a system such as system 31 into the FTL but the odds movements would mean I would lose a helluva lot of the edge this system has at Friday afternoon prices. Over the last 3 live seasons, system 31 has achieved an average profit of 52.5pts per season.  With Friday afternoon prices, I expect this profit would be circa. 30pts lower. This is a massive swing and therefore, my concern is that if system 31 has an average season (might be due one!), this system will make a loss in the FTL.

I think many of my subscribers probably assumed system 31 would be the FTL system this season but I’m worried I jinx the system! If system 31 has a poor season this season, most of us will be licking our wounds and therefore, I’d rather not take the risk. :)

So, my 2014/15 FTL bounty system will be …….. System D1-D6.

Yip, after only one live season of results, I’m going with a UK Draw system as my FTL system this season.

It was a straightforward decision if I’m honest. I know that Pinnacle offer the most competitive draw prices and I know from last season that my Draw systems don’t move the market much at all (maybe a little bit this season as some more people will be following them) and therefore, a Draw system gives me the best chance of competing in the FTL.

In terms of deciding on what UK Draw system to follow, here are the results from the Draw systems last season:


Well, quite quickly, we can rule out systems D1, D3, D6, D3-D6 and D3-D7. All 5 systems didn’t do that great last season and I’d not have much confidence in any of these systems next season.

Looking at the systems that were left, it’s not easy to choose the ‘right’ system. I think the thing that made me choose D1-D6 was simply the turnover. The system had 390 bets last season and I think about 400 bets is a good number of bets for a FTL system.  Last season, a profit of 44pts was achieved and if we look at the FTL over the past 3 seasons, this system would have walked the league each season if a profit of 44pts was achieved. Importantly, I did a quick check of this system based on the same odds as the FTL use (shows I’m trying my best this season!) and this system achieved around 43pts profit last season. No real impact from the prices quoted on a Friday.

The aim is simple with this system. 400 bets and an ROI of 10%. All it has to do it repeat the performance from last season and it will surely finish high up in the FTL this season. 

Before we all get too excited, the backtested results of the FTL system I used last season were better than this and the system flopped badly when it went live. I guess the difference for this season is I have a season’s proofed results underpinning this system and therefore, I have to be fairly hopeful I have a system which can win the FTL. That’s the aim!

FTL Other System

I think the other thing I learnt last season was not to put all my eggs in one basket! Given there is a really good prize on offer in the FTL, I think it is worth having a back-up system in the league.  To be clear, this back-up system has no bounty attached to it and therefore, it is going to be a very high risk system. Similar to my other system in the FTL, it will be a live TFA system but this system has no live results behind it and season 2014/15 will be the first live bets for this system.

Well, anyone with the service will know which type of bets this system will have. Given what I discussed above about odds movements, it’s no real surprise that I’ve gone down the Draw system route again.

Season 2014/15 sees my first foray into the European Leagues with Draw systems and therefore, this will be direct competition to Cassini’s own Draw system for these Euro leagues.  I’m sure Cassini doesn’t mind a little bit of competition. :)

Given I have no live results to go on, picking which system to follow from the European Draws is a bit of a punt.

Similar to what I concluded with the UK Draw systems, I think I’m forced to go for system DE1-DE6. The system is expected to have around 300-350 bets a season and I guess my hope would be that it can achieve an ROI of around 10%. Given I don’t expect any odds movements with these Draw bets (very few subscribers will be following these new bets), I don’t need to worry about the odds quoting impacting the returns too much.

Given my Euro systems flopped in their first season, I wouldn’t be totally surprised to see the Euro Draw systems flop next season. Of course, I hope this isn’t the case and the backtested results are very positive but I’m always wary of the Euro leagues after what happened to my Euro bets in their first season. What I would say is I managed to rebuild the Euro ratings based on what I learnt in the first season and the second season was much more profitable, so I’m hopeful I have a better handle on the Euro leagues than I had when the Euro systems first went live. We shall see.

So, to summarise, the TFA FTL Bounty system next season will be system D1-D6. The other FTL system will be DE1-DE6.

Let battle commence……..

Portfolio Probabilities

One of the most common ways to play TFA each season has been to follow a number of systems in a portfolio. Until last season, it had been a fairly simple way to make a profit each season and given the large % of systems profitable each season, it was quite difficult to make a loss over the first 3 seasons if using this approach.

Anyone who was reading Steve’s Daily 25 blog will have seen the issues Steve had last season with following a portfolio approach and ultimately, Steve followed 13 systems last season and somehow managed to hit 7 of his 13 systems to be loss making. Given that 35 of the 52 TFA systems live last season were profitable (67%), the odds were obviously in Steve’s favour in terms of randomly selecting a portfolio of systems to follow and being able to make a profit. 

I thought it was worth a very quick blog post to show the probability of making a profit for each season based on the number of systems in your portfolio. Of course, the key thing with this analysis is that the portfolio selection is 100% random and I’m not aware of any TFA subscribers who randomly select a portfolio of systems to follow each Summer. Given these results below, I think it does show that if you follow a small number of systems in a portfolio, you could do a lot worse than randomly selecting the portfolio. Based on the losses that some subscribers suffered last season from following correlated systems in a portfolio, a random selection approach is a much better method than following correlated systems!

2010/11 Season

There were 11 live systems in the first season. All 11 systems were profitable with an average profit of 23.9pts.

Here’s table showing your expected profit and expected probability of your portfolio making a profit based on the number of systems you followed:


Hardly anything too surprising here. No matter how many systems you followed, you were guaranteed to make a profit given every system was profitable.

2011/12 Season

There were 22 live systems and 21 systems made a profit (system 33 made a loss). An average profit of 21.8pts was achieved across all 22 systems.

Here’s the same table as above:


If following 1 system, you had a 95.3% chance of making a profit. If anyone followed system 33 in isolation during this season, they deserve to make a loss! Basically, by the time you get up to following 2 or more systems, you were pretty much guaranteed to make a profit on the season.

2012/13 Season

There were 41 live systems and 8 systems were loss making. All UK systems were profitable but the Euro systems were very poor in their first season. An average profit of 19.6pts was achieved across all 41 systems.

Here’s the same table again for this season:


Starts to get more interesting here and if you only followed one system, you had an 80.5% chance of hitting a profitable system. You needed to be following at least 4 systems to achieve a 90%+ probability of your portfolio being profitable.

2013/14 Season

There were 52 live systems last season and 35 of them made a profit. An average profit of 11pts was achieved across all 52 systems.

Here’s the table again:


If following 1 system, you had a 67% of hitting a profitable system. Even if following 3 systems, you only had an 86.7% chance of hitting a profit.

If we take the example of Steve (Daily 25 blog) from last season, Steve followed 13 systems and based on the numbers above, the chance of Steve making a loss following 13 RANDOM systems last season was less than 1%. However, as I mentioned at the start, Steve’s portfolio was anything but random and was actually heavily correlated. Hence, when one of Steve’s bets lost, it ended up pulling down lots of systems and therefore, his portfolio wasn’t random and therefore, the chances of making a loss were much bigger than outlined in my analysis.

I guess the other trend to pick up is that as I have grown the number of systems season on season, the number of losing systems in a season has grown and therefore, if you were randomly selecting one system to follow, you have more and more chance of hitting a losing season. I saw that last season as I know someone who has followed 7-22 since day one and after 3 profitable seasons, they hit a losing season last season.

However, if you have followed 5 random systems each season since inception, you would have had a 90%+ chance of making a profit each season.

What will 2014/15 season hold for us using a portfolio approach?  Ideally, I’d like to see all 61 systems make a profit next season but then again, I know it’s highly unlikely for this to happen but we’ll see what happens.

Here’s a summary of all 4 seasons below in one table.  Will be interesting to see how season 5 compares next Summer……

TFA Value Ratings

What I intend on doing this Summer is that when people write to me and our discussions sparks off a piece of analysis or an interesting angle to look at, I’ll try to do a blog post on the subject. These posts aren’t going to be too long and ultimately, what I want people to take from these posts is to consider whether or not it’s another angle they may want to look at this Summer.

David wrote to me on Friday with some analysis he’d been looking at on the TFA value ratings. Interestingly, rather than looking at the ratings in terms of value bands as I’d been doing, David was looking at 1% increments and had noticed that there was a clear trend that bets under 1% were terrible value and badly loss making and should be removed from the systems immediately.

I mentioned in the previous post that at times, I can’t see the wood for the trees as there are so many ways to analyse TFA, it’s easy to overlook something fairly obvious.  I think this is another example of me potentially overlooking something that was fairly obvious.

As always, when looking at the data from the algorithms and systems, we need to decide which data to look at. When we are looking at the value ratings, we have a number of options to look at.

All single systems (6,7,8,21,22,31,32,33,41 & 42) from 2010/11 to 2013/14
All live bets from 2010/11 to 2013/14 (6,7,8,21,22 for 4 seasons, 31,32,33 for 3 seasons and 41,42 for 2 seasons)
All bets for rating algorithms only (6,21,31 & 41) from 2010/11 to 2013/14
All live bets for rating algorithms only from 2010/11 to 2013/14 (6,21 for 4 seasons, 31 for 3 seasons and 41 for 2 seasons)

Clearly, we would also like to look at 2013/14 season in isolation and therefore, we have the following two options:

All live bets from 2013/14 season (6,7,8,21,22,31,32,33,41 & 42)
All live bets for rating algorithm only from 2013/14 season (6,21,31 & 41)

I think we have 6 different splits we can look at. Obviously, the bets from the 2013/14 season are the most indicative but as we know, last season was anything but a normal season and therefore, I wouldn’t like to draw too many conclusions from last season’s data in isolation although it will be interesting to see how the results looks.

Rather than analysing tables of data, I am going to use graphs. The vertical graph will be cumulative ROI and the horizontal graph will be the TFA value rating. Clearly, we would expect to see ROI increase as we move along the TFA value axis.

All single systems (6,7,8,21,22,31,32,33,41 & 42) from 2010/11 to 2013/14


As we can see, backing bets with between 0% and 1% value has created a near 17% loss over the 4 seasons of results. Backing all bets up to 5% value is basically break-even which is where my thinking was about missing out these bets this season.

All live bets from 2010/11 to 2013/14 (6,7,8,21,22 for 4 seasons, 31,32,33 for 3 seasons and 41,42 for 2 seasons)


Again, backing bets with between 0% and 1% value has created a near 20% loss for the live systems over the last 4 seasons. Backing all bets up to 9% value is basically break-even.

All bets for rating algorithms only (6,21,31 & 41) from 2010/11 to 2013/14


Again, backing bets with between 0% and 1% value has created a near 175% loss for the live systems over the last 4 seasons. Backing all bets up to 5% value is basically break-even.

All live bets for rating algorithms only from 2010/11 to 2013/14 (6,21 for 4 seasons, 31 for 3 seasons and 41 for 2 seasons)


Again, backing bets with between 0% and 1% value has created a near 16% loss for the live systems over the last 4 seasons. Backing all bets up to 5% value is basically break-even.

All live bets from 2013/14 season (6,7,8,21,22,31,32,33,41 & 42)


Backing bets with between 0% and 1% created a near 16% loss for the systems in the 2013/14 season. Backing all bets up to 16% value is basically break-even.

All live bets for rating algorithm only from 2013/14 season (6,21,31 & 41)


 Backing bets with between 0% and 1% created a near 9% loss for the systems in the 2013/14 season. Backing all bets up to 13% value is basically break-even.

Ok, there is probably a lot to take in here, so let’s try to break it down a little.  In summary:
  •        There is clear correlation between the level of profitability achieved and the TFA value ratings.
  •        The higher the TFA value, the higher the ROI achieved.
  •        It seems a no-brainer to drop all bets of less than 1% value on all algorithms given that for every season, these bets have been badly loss making.
  •       The 2013/14 season was clearly a tougher season than the previous seasons for the ratings and this has been replicated in the value ratings. However, if you had been filtering out the lower value bets, you could have eliminated some of the areas where losses were made.
  •       I would suspect that there is clear correlation between the underlying results for a season and where the value ratings break-even. During a very tough season like last season, if backing all bets, you needed to set the value % fairly high. During easier seasons, your value % could be lower before profits will be made. We won’t know this in advance, so people need to set their value cut-off where it suits them I think.
  •       Clearly, the value ratings provide a filter that appears to be fairly powerful

The ratings were under utilised last season by myself and many other subscribers. Given the issues the systems faced and the fact there was a very easy way to filter out some poor value bets, I’m frustrated by this and from exchanging emails with some subscribers who used the ratings, I’m even more frustrated that these people did much better than everyone else! Basically, during a really difficult season last season, all the info was available to all of us to do much better than we ultimately did and we need to learn from this going forward.

Starting later and finishing sooner......

One question that continually crops up in my email box every Summer when I start helping subscribers out with advice for the season ahead is around whether my ratings are as potent at the start of a season and the end of a season.

I remember covering this a few years ago after the second season started horribly in September 2011 but based on the backtested data and live results then, I didn’t think there was anything in it. I remember the same discussion last Summer after the season ended badly in May 2013 and I decided that there were so few bets in May, it is impossible to really draw any conclusions.

Roll on another season and we now have 4 seasons of live results and shock horror, yesterday, someone asked me this very question when they saw the historical results for their portfolio and the fact that September and May were not making any money for their portfolio over the last 4 seasons and therefore, should they consider waiting until a couple of more games are played in each league and stopping the season when there are two games left?

Now, before I share the updated results by calendar month, my own view remains unchanged. I don’t think we can predict when my ratings will work and when they won’t work and the same goes for any subset of bets. A few people are still licking some significant wounds after dropping League Two Aways last season as after all, with losses over the first 3 seasons, surely my ratings had no edge in that league…..wrong!  League Two Aways were the best subset of bets by far last season and a massive correction took place after 3 very poor seasons.

I think the difference between something like League Two Aways poor performance and the poor performance at the start and end of the season is that I had no explanation for the performance of League Two Aways as I admitted. League One Aways were fine, Conference Aways were fine and therefore, it was always a little puzzling that League Two Aways were loss making. I think it’s not too difficult to come up with a theory of why my ratings may not work at the start of the season (after 6 games) and at the end of the season.

Before we start trying to come up with theories, let’s see the updated results of all live system bets since inception of the service (I’ve excluded Under/Over bets as they are no longer part of the service):


 Now, I can imagine people are starting to lick their lips at this picture and will be thinking that they have an extra few weeks off this Summer as they are not starting following the bets until October but I’m not sure it’s as straightforward as this if I’m honest.

I think it maybe helps to look at the breakdown by season first and then come back to the overall results. Here’s the breakdown by season and month:


I always think it’s interesting to look at all TFA results like this as there are so many systems and different types of bets, looking at things at a high level sometimes helps as at times, you can’t see the wood for the trees.

I think the key point from this for me is the fact that every season, there has been a month or two that has been a disaster. In season 1, it was February and April. In season 2, it was September and February. In season 3, it was January and May. In season 4, it was September and March.

So, we have 2 Septembers, 1 January, 2 Februarys,1 March, 1 April and 1 May.  8 shocking months over 4 seasons.

When you look at the overall results for each month above, only September and May have been loss making over the 4 seasons. So, although February had two poor months, it has also had 2 amazing months and therefore, the overall month looks fine!

We can see September has also had an amazing month in Sep-12 but two amazingly bad months in Sep-11 and Sep-13.

May has only really had one shocking month in May-13 but apart from this, May has been OK.

Can we read too much into this?

Lastly, before we try to draw any conclusions, as we know from last season, we can’t ignore the underlying results as at the end of the day, no matter how good or bad my ratings are, they will be impacted by the underlying trends in results.

Here’s the underlying results for the last 4 seasons by month:


I think we have everything we need to start to draw any conclusions.

If I deal with the underlying results first, I think we can see that November is the easiest month of the season for the last 4 seasons based on the underlying results and therefore, it’s no great surprise to see November’s TFA results being so strong.

However, beyond this, it gets difficult to blame the underlying results for the mess we’ve seen with the TFA bets in September and May. September is not an easy month by any means but when you look at January to April, you’d have to say that all 4 months are tougher than September and yet, my ratings cope no bother in these months.

May is a funny month as based on the underlying results and the big Away bias in the month, I’d bet my systems would do great but unfortunately, this isn’t the case. I find this more interesting than September if I’m honest and possibly, there may be something about May which nullifies my ratings to a degree. Again, you wouldn’t need to be a conspiracy theorist to think it’s a motivational thing going on here but again, it’s difficult to be sure.

Overall, I’m not sure the Underlying results are to blame for the issues in either September or May and therefore, I can’t use this as an excuse.

I guess after 2,749 bets in September, it may appear to be the case the ratings have no edge in this month but I think when you know this is based on only 4 seasons of results, it’s difficult to know for certain that no edge exists.

I say this a lot with TFA but it is up to each individual with the service to determine which bets they have and whether or not they decide to start later or stop earlier in the season. I personally will be hoping the systems get off to an amazing start in September and I really hope those who don’t start placing bets then will regret their decision but on the other hand, as long as people have made the decision based on the data and their own thoughts, then no one should worry too much about September results.

I guess deep down, my own issue would be that we can see from the results that the systems have an amazing month 3 or 4 times a season. Hence, if I drop a month, this means that there is a good chance this month may be September or May and therefore, my P&L will be badly impacted for the season. On the other hand, if anyone drops September and it’s a nightmare month, I can guarantee they will have a decent season as if you can dodge a nightmare month, you should have a great season!

Is it worth the risk? IMO, definitely not and having seen these results, I may decide to play smaller stakes nearer the end of the season and I’ll be keeping a very close eye on September to see how it goes this season but I’m not sure I could cope if September 2014 ended up like September 2012 and I didn’t have any bets that month.

What do others think? Are 4 data points enough to draw conclusions about monthly performance? Do people buy into this idea that ratings may not work at the start of the season (I wait 6 games, others wait 8 or 10 games) and therefore, are they happy to sit out the first few weeks of bets?

As always, the above is my view and if September is a nightmare again, please don’t blame me. I give you the data and results, it’s up to all of you to determine what you do with it…….

Review of SBC TFA Portfolios

For those reading the blog or subscribing to the service that are not Secret Betting Club (SBC) members, one of the things I did last season was construct 10 example portfolios of TFA bets that I tracked every month in the SBC forum. The main reason for doing this was that I wanted to highlight to SBC forum readers that:

  •         TFA provides subscribers with the ability to achieve a decent level of return on capital from the service due to the sheer number of systems available to follow
  •        Constructing a TFA portfolio isn’t that difficult and anyone can do it
  •        Turnover is much more important than ROI when it comes to achieving a decent return on capital for a betting portfolio
  •        Lastly, I hoped to be able to demonstrate that no matter how you followed the service last season, you should have been able to make a profit 

Of course, as regular blog readers will be aware, last season didn’t exactly go to plan for TFA and for the first season since inception, some systems had a losing season. This had a knock-on effect on these portfolios and therefore, for the low turnover portfolios, the season was a real struggle.

The purpose of this post is to provide a quick overview of how the season went generally for the portfolios and for the first time, to share which systems were part of each portfolio. I didn’t share the systems which made up the portfolios with the SBC forum members although of course, I shared the systems with Peter Ling of the SBC. The purpose of the forum thread wasn’t to get people to follow the bets, it was to show how powerful (or not!) a portfolio approach could be with TFA.

There has been a lot of talk last season on this blog and other blogs about whether or not a portfolio approach is an appropriate way to follow the TFA systems. I’ve always made my feelings well known on the subject and for me personally, this is the way that I like to follow the systems.  For me, the 3 main benefits of a portfolio approach are:

  •      Diversification – You are not putting all your eggs in one basket by following one system, one algorithm or one type of bets
  •      Leverage – You can make your betting bank work harder for you. For example, a system may need a 50pt bank and yet, 3 systems combined may need a 100pt bank.
  •      Increased Returns – This is linked to leverage I think but if you are following multiple systems from a combined betting bank, there is potential to increase your return on capital

I think after the first 3 seasons following the systems this way, I honestly believed that if you followed a decent number of systems in a portfolio, you couldn’t lose following TFA. Of course, this was based on the premise that every system would be profitable every season and the more bets you followed, the more money you made and therefore, TFA was the greatest thing since sliced bread.

Roll on 12 months and not surprisingly, my views are not as strong as they were last Summer. I still believe TFA to be the greatest thing since sliced bread but I now appreciate that a losing season for a system is not as remote a possibility as I thought previously. Therefore, if a system can have a losing season, a portfolio with a number of losing systems can have a losing season and therefore, the TFA portfolio approach is not as infallible as I thought it was.

However, I do think if you follow some basic rules about building a portfolio, it is still a decent method but like any betting method, if you don’t put enough thought into it or don’t appreciate the risks fully, it can go wrong.

OK, so here are the overall results for the season for the 10 portfolios I tracked in the SBC forum last season:


I think the first point to make is that only 7 of the 10 portfolios managed to make a positive return last season. This alone is disappointing to me but I think when you see which portfolios lost money, we can probably learn from this experience.  The 3 lowest turnover portfolios lost money last season as quite simply, they didn’t have enough bets. If you rely on 3 systems, you aren’t actually getting that much diversification at all and as I’ll discuss below when I look at each portfolio in more detail, there was not enough diversification in these lower turnover portfolios at all. Hence, they were probably not much better than just following a single system and as I said above, a single system can make a loss over a season.

I think the other thing that jumps off the page here is the months of Sep-13 and Mar-14. Anyone following the blog last season as well as those following the system bets themselves will be aware of the difficulties the systems had in both these months generally as the underlying results were very tough and we can see that impact magnified to a degree here as we’re looking at combinations of systems. Obviously, both of these months were a bit of a nightmare but I think it’s interesting that even during a really poor season for the systems and a tough season generally for football betting, 7 of the portfolios achieved a profit.

I guess the other point I’d make is that even though 3 portfolios lost money, the losses were very small. The worst system lost 11.2% of its betting bank over the season. The lowest ROC for a profitable portfolio was 25.9%. The average ROC for a losing portfolio was 8%, the average ROC for a winning portfolio was 59.6%.

I think the other point worth making is the ROI. I came up with the phrase a few years ago ‘ROI for show, ROC for dough’ and I think we can again see this in play here. Portfolio 1 managed to make an ROI of 5.3% which for some people, may not seem like a decent ROI for football systems but when you see this is achieved across 2,157 bets, it suddenly doesn’t appear too bad as the ROC is 91.6%.  A bank growth of 91.6% for a really poor season and the worst season of the 4 so far doesn’t look too bad now does it?

OK, I’ll quickly run through each portfolio and comment on the individual system results in each portfolio and the overall returns for the portfolio.

Portfolio 1

This portfolio contains 7 systems and the portfolio is fairly well diversified. It contains 3 Est Systems (21,7-21 and 8-22), 1 New System (31), 1 Misc System (STOY), 1 Draw System (D1-D6) and 1 Euro System (E2-E7). 

With hindsight, I’m not sure what system 7-21 and 8-22 bring to the portfolio apart from extra correlation as the bets will already appear on system 21. I would probably throw in a European Draw system next season and remove 7-21 and 8-22 if I was adjusting this portfolio next season.

In terms of results, here’s the results by system:

21  = 11.9pts
7-21 = -16.8pts
8-22 = -9.1pts
31 = 56.9pts
STOY = 21.4pts
D1-D6 = 44pts
E2-E7 = 6.2pts

Overall, a profit of 114.5pts, an ROI of 5.3% and a ROC of 91.6%.

On one hand, I’m disappointed with the results as based on historical results, I would have expected a higher level of ROC. However, considering how tough the season was and the fact this is the toughest of the 4 seasons to date, I don’t think I can moan too much about the level of returns. With hindsight, I’m not even sure what systems 7-21 and 8-22 are doing in the portfolio as they don’t bring any additional diversification and as luck would have it, these two systems are the ones pulling down the performance of the portfolio.

Portfolio 2

This portfolio contains 7 systems and the portfolio is again fairly well diversified. It contains 3 Est Systems (21,6-21 and 7-22), 1 New System (31-41), 1 Misc System (STOZ), 1 Draw System (D2-D6) and 1 Euro System (E2-E6). 

Similar comments to portfolio 1 really as I’m not sure why we need 6-21 and 7-22 in the portfolio. I would keep either 21 or 6-21 and bring in a new European Draw system to replace the lost turnover.

Here’s the results by system:

21  = 11.9pts
6-21 = 12pts
7-22 = -11pts
31-41 = 41.9pts
STOZ = 8.8pts
D2-D6 = 36.3pts
E2-E6 = 13.9pts

Overall, a profit of 113.9pts, an ROI of 5% and a ROC of 75.9%.

Only the one losing system in this portfolio and again, it is probably one system that shouldn’t even be in there. I think a few key systems in here had a below par season (21 and STOZ) and during a more normal season, the returns would have been better I think. Even so, a 75.9% ROC is not too bad during a really tough season.

Portfolio 3

This portfolio contains 7 systems and the portfolio is again fairly well diversified although there were no Euro bets in this portfolio. It contains 2 Est Systems (6-21 and 8-22), 2 New Systems (31,33-41), 2 Misc Systems (STOY, TOX), 1 Draw System (D3-D7).

With hindsight, I would replace either STOY or TOX with another Misc System (6-32 probably) or replace it with a Euro system. I would also bring in a Euro Draw system. 

Here’s the results by system:

6-21 = 12pts
8-22 = -9.1pts
31 = 56.9pts
33-41 = -10.1pts
STOY = 21.4pts
TOX = 11.5pts
D3-D7 = 1.7pts

Overall, a profit of 84.5pts, an ROI of 4.4% and a ROC of 56.3%.

2 losing systems, a poor selection of a draw system and an under performance of 6-21 and TOX and yet, the portfolio made 56.3% ROC. I think this is as good an advert for a portfolio approach as you can get! Lots of mistakes made in the selection of the systems but at the end of the day, we will never choose the correct systems. I think with a portfolio approach though, you can limit the damage by having more systems in there or in the case of this portfolio, you can actually still achieve a good return during a horrible season!

I would probably remove STOY or TOX and include a Euro System and maybe throw in a Euro Draw system too.

Portfolio 4

This portfolio contains 6 systems and the portfolio is less well diversified as there are no Draw or Euro bets included. It contains 2 Est Systems (6-21 and 8-22), 1 New System (31-41) and 3 Misc System (STOY, STOZ and 6-21-31)

My thinking when I built this portfolio was to concentrate solely on the UK bets and put an emphasis on the Misc systems. The first 3 portfolios had more emphasis on the Est and New Systems. Looking at it again, I would probably only keep STOY or STOZ and of course, with no Euro or Draw bets, there is plenty of room for more diversification and turnover if wanted.

Here’s the results:

6-21 = 12pts
8-22 = -9.1pts
31-41 = 41.9pts
STOY = 21.4pts
STOZ = 8.8pts
6-21-31 = 25.4pts

Overall, 100.4pts profit, an ROI of 4.7% and a ROC of 66.9%.

Only one losing system in here but it’s a fairly strong performance from this portfolio. With hindsight, having STOX and STOY in there probably doesn’t make sense and with hindsight, having seen the returns of the top 3 portfolios, I’m definitely favouring the route of more diversification across other bets (Draws and Euros) but for a UK specific portfolio, this one isn’t too bad.

Portfolio 5

This portfolio contains 6 systems and the portfolio is slightly more diversified than portfolio 4 but there are no Euro bets included. It contains 2 Est Systems (21 and 7-21), 1 New System (31-42 and 33-42), 1 Misc System (STOZ) and 1 Draw system (D2-D7)

This is the first portfolio with a much lower turnover as some of the systems are getting to be more selective. Again, it’s easy with hindsight to say I’d change systems but I think for the purpose, this portfolio is OK.

Here’s the results:

21 = 11.9pts
7-21 = -16.8pts
31-42 = 4.2pts
33-42 = -9pts
STOZ =  8.8pts
D2-D7 = 39.8pts

Overall, 38.9pts profit, an ROI of 2.6% and a ROC of 25.9%.

With 2 losing systems, 2 systems which performed poorly and one system below par, it’s amazing any profit was made at all here, never mind a 25.9% ROC! You make your own luck at times and I guess by including an unproven Draw system in here, this made this portfolio last season. All of the profits came from the Draw system which going into the season, had no live results!

A really poor performance from this portfolio but if this can happen during a poor season, it can only get better I suspect!

Portfolio 6

This portfolio only contained 5 systems but I would say it was fully diversified unlike a few of the previous portfolios. It contains 1 Est System (6-21), 1 New System (31-42), 1 Misc System (STOY), 1 Draw System (D2-D6) and 1 Euro System (E3-E7).

I like this portfolio. I liked the idea of one system from each group of systems although I’d probably switch 31-42 for 31-41 and I’d probably switch the draw system to D1-D6 and bring in a new Euro Draw system too in future.

Here’s the results:

6-21 = 12pts
31-42 = 4.2pts
STOY = 21.4pts
D2-D6 = 36.3pts
E3-E7 = 5.1pts

Overall, 79.1pts profit, 6.3% ROI and a ROC of 63.3%.

I like this portfolio idea. I like the way the risk is spread evenly across all systems although as always, it is probably taking a bit of a chance with putting equal weight on the Euro and Draw systems given their lack of live bets thus far but again, it worked out fine.

Portfolio 7

This portfolio only contained 5 systems and it was fairly well diversified (No Euro Systems) although we are now into the portfolios that had lower turnover. It contains 1 Est System (6-21), 1 New System (32-41), 2 Misc Systems (21-31, STOZ) and 1 Draw System (D3-D7).

Here’s the results:

6-21 = 12pts
32-41 = -0.7pts
21-31 = 24.4pts
STOZ = 8.8pts
D3-D7 = 1.7pts

Overall, 46.3pts profit, 3.1% ROI and a ROC of 37%.

This portfolio struggled a little with system choice. 32-41 rather than 31-41 dented profits massively, D3-D7 rather than of the other first 4 combined draw systems (D1-D6 thru to D2-D7) dented profits massively and STOZ was poor in comparison to TOX and STOY.

Again though, difficult to be too critical of a portfolio that makes 37% ROC during a really poor season for the systems in general.

Portfolio 8

This portfolio only contained 4 systems and 3 of the systems were more of the selective systems amongst the combined systems. Hence, given the issues we had with filtering the system bets, these portfolios are going to struggle last season.

The 4 systems were 1 Est System (7-21), 1 New System (33-41), 1 Misc System (STOY) and 1 Draw System (D3-D7)

The results were:

7-21 = -16.8pts
33-41 = -10.1pts
STOY = 21.4pts
D3-D7 = 1.7pts

Overall, -3.8pts, -0.7% ROI and -4.8% ROC.

When 50% of the portfolio contains the worst Est System and the worst New System (not easy to do considering there were 66 possible pairs of these systems!), it is unlikely to be a good season!

With hindsight, following a lower number of systems in a portfolio isn’t the worst idea in the world but following very selective systems in a portfolio opens up the door to variance as you don’t have enough turnover to overcome the variance.

My own view is that if you are following a portfolio approach, you need to ensure you have enough unique bets to make it worthwhile. This portfolio along with the other two losing portfolios didn’t have enough bets last season IMO.

Portfolio 9

This portfolio only contained 3 systems these were more of the selective systems amongst the combined systems. Hence, given the issues we had with filtering the system bets, these portfolios are going to struggle last season.

The systems were 1 Est System (7-21), 1 New System (32-42) and 1 Misc System (TOX).

The results were:

7-21 = -16.8pts
32-42 = -2.7pts
TOX = 11.5pts

Overall, -8pts, -1.3% ROI and -8% ROC.

Again, when 2/3 of the portfolio contain losing systems, you can’t expect to have a winning season! Not enough bets and not enough systems.

Portfolio 10

This portfolio only contained 3 systems these were more of the selective systems amongst the combined systems. Hence, given the issues we had with filtering the system bets, these portfolios are going to struggle last season.

The systems were 1 Est System (7-22), 1 New System (33-42) and 1 Misc System (STOZ).

The results were:

7-22 = -11pts
33-42 = -9pts
STOZ = 8.8pts

Overall, -11.2pts, -2.2% ROI and -11.2% ROC.

I think after writing the above reviews, there are some additional points I would add when building a portfolio approach to following the TFA systems:
  •         Think about what each system brings to your portfolio. Don’t just add systems for the sake of adding systems. If it doesn’t bring you diversification, leverage or increased returns, don’t add the system!
  •         Following 3 or 4 correlated systems in a portfolio with a very low overall turnover of unique bets is not a portfolio approach at all and is no better than following one system (and is probably worse!)
  •         To benefit from a portfolio approach, you need to follow a decent number of systems and of course, the more diversification you have, the better
Hopefully this post gives a good case for following a portfolio approach to TFA but as always, if used incorrectly, it can go badly wrong I think!
