As a one-off this month, I’m going to spend a bit of time
discussing the trends within the underlying results we have seen this season. By
underlying results, I simply mean the results of betting 1pt win on every Home
selection, every Away selection and every Draw in all UK games I’ve rated so
far this season.
I personally have always kept OK records of the
underlying results for all UK leagues as I download the data from
footballdata.co.uk like most playing this ratings game but I was aware that my
results analysis was probably not as detailed as some others in this game. Therefore,
I’ve spent a little bit of time pulling together the underlying results in a
little more depth than I was doing before. The purpose of this is so I can look
at the trends in a little more detail and therefore, I’m going to share some of
my findings in this post. I also have the tables set up so I can refresh them easily in future.
I’m sure some reading this will be thinking that I’ve
went down this route to try to find excuses for my results this season and in a
way, that is partly true. I do believe my ratings still have an edge and
therefore, I have to believe that there are other factors at play this season.
When I look at the underlying results, I can see where the issues are and therefore, I think it helps me to understand what is going on this season. Of
course, it doesn’t change my results and at the end of the day, I’m judged on
the results the systems achieve and so far this season, they haven’t been good
enough.
OK, I think the first point to make is that I always
simply use the best price from a host of bookmakers in the data from
footballdata.co.uk. Given I don’t use best prices for my own system bets, I
could never match the returns quoted in the underlying results but that’s
immaterial really. The purpose of this is to look at the trends rather than the
specific numbers. I have concentrated my analysis on the last 3.5 seasons as
this is when I started betting on football but I have the data going back
further. The issue with going back further is the football odds aren’t quite as
competitive and the results from 10 years ago are much worse overall than the
last few seasons, so let’s keep this analysis to when I started rating games
myself which was the 2010/11 season. All
data is to the end of Jan-14.
Let’s firstly look at the results by season, split
between Homes, Aways and Draws.
OK, there is a lot to take in here, so let me explain
what this table shows. It shows the games rated, the % wins for Homes, Aways
and Draws and then the corresponding ROI for backing all Homes, Aways and Draws.
It also shows an overall ROI which would be the result if you had placed 1pt on
the Home, Away and Draw for every game I’ve rated. At the right-hand side, it shows the ROI for
each of my 4 algorithms for each season. I have only looked at live results, so
alg 3 missed the first season and alg 4 only started last season.
I think the first thing that stands out is the fact that
all 4 of my algorithms are underperforming this season compared to previous
seasons. Two of the algorithms are actually loss making this season and so far,
I’ve never had an algorithm make a loss over the season. None of the algorithms
are having a disaster though and losing 1% and 0.6% across a high number of
bets is no disgrace. The other two algs are showing a small profit.
Looking at the underlying results then, you can see that
for Homes, this is the first season where following all Home bets hasn’t made
between a 3%-5% loss. So far, backing all homes has made a 0.2% profit. In
terms of Aways, the first two seasons lost just under 2% before last season’s
freak season where backing all Aways made a profit of 7.4%. This season though,
something of a freak again where backing all Aways has made a loss of 6.7%.
In terms of Draws, these have performed slightly worse
this season than the last 3 seasons and have lost 4% so far which is the worst
season of the 4. In terms of overall
ROI, the loss this season is the worst of the last 4 seasons (last season
showed a profit which was an amazing stat!) and if backing 1pt on every Home,
Away and Draw this season, you would have lost 10.6% of your stakes.
What does all of this mean in the context of the TFA
ratings and TFA systems? Well, around
65% of all TFA bets are Away bets. It is slightly more confusing this season as
I have Draw bets too but before this season, it was quite steady at a 65% split
for Aways and 35% for Homes. Therefore,
if there is a bias against Aways (in the sense, it is more profitable to be
backing Homes), then this means it will impact my ratings and systems.
However, it isn’t as easy as this to understand the
impact on my ratings this season. If we look at the returns by odds range, it
gets even more difficult for my ratings.
Here’s the returns by odds range for Homes:
As this split shows, backing all odds on homes has shown
a profit of 7.3%. Unfortunately, my ratings and systems don’t tend to find much
value in odds on home bets (traditionally, more difficult to recognise value
for this odds range) and therefore, a very small percentage of my home bets are
odds on. However, my ratings do find plenty of home bets priced 2.00+ and
therefore, even though backing all Homes has been a marginally profitable
strategy this season, my ratings and systems are not really playing too much in
this odds range and therefore, the home bias isn’t picked up by the systems as
much as I would have hoped this season. Many of my home bets are priced 3.00+ too which compounds the issue.
Here’s the returns by odds range for Aways:
Now, this is where my ratings and systems have a second
issue. Historically, finding value in away bets priced 2.75 or lower is
difficult according to my rating algorithms and therefore, I basically have a
filter on all systems which kicks out all away bets at 2.50 or below even if my
ratings find value in the bets. Not only that, after the poor performance of
these Aways in the first season of live bets, I decided 2.75 was a better
cut-off and therefore, I very rarely give out Aways at less than 2.75. Hence, I
have missed out on the best performing Away bets this season too!
90% of my Away bets are priced within the odds range of
2.75-6.00 and as you can see, trying to make a profit in this price range this
season has been very difficult. An overall loss of 9.1% for all of these bets.
OK, summing together the findings for the Home and Away
bets by odds range, it starts to paint the picture of what has happened to my
ratings and systems this season! Homes may be profitable overall but I am
missing out most of the profitable bets and Aways losses would have been
minimised if I had been backing short-priced Aways in addition to my usual
bets.
What does all this mean in the longer-term? Well, it doesn’t mean anything I think!
Nothing I’ve seen this season has changed my findings longer term that it is
very difficult to make money backing odds on Homes and short priced Aways. I do
track the system bets (loosely) which don’t make the cut due to the odds being
too short and over the first 3 seasons, both odds on Homes and short priced
Aways were loss making. This season,
both sets of bets are showing a good profit but that’s simply due to the
underlying conditions being easier than normal.
I think the other thing I’ve learnt a lot about over the
first few years betting on football is that you need to go against the crowd to
make money long-term and maintain a long-term edge. Backing odds on Home bets
may be doing great this season but long-term, there can’t really be an edge
backing the favourites all the time and they just don’t represent value.
Likewise, backing favourites Away from home isn’t a strategy to make money and
it’s not the type of bets that my ratings work well on.
Below is a table I’ve pulled together. Admittedly, if I
had more time, I would have split the data between Homes and Aways but I
decided to stick with the overall results.
This table shows the same data I showed earlier by season
but splits it by month. I’m not expecting anyone to be able to do any
statistical analysis to show that there is perfect correlation between my
algorithm results and the underlying results but I think this table allows us
to make some observations.
Clearly, when there is a large loss for the underlying
Away results, generally, it is more difficult for my rating algorithms to make
a profit. We can see that in Sep-13 this season. Aways lost 17.4% and my 4
algorithms lost 9%-30% each! The same is true for Jan-14 where Aways lost 16.9%
and 2 algorithms made a loss. March-13 saw another 2 algorithms make a loss and
then Feb-12 saw all 3 algorithms suffer large losses as Aways lost 16.2%. Going
further back, we can see the same in Jan-11 and Apr-11 where Aways suffered
large losses and the algorithms suffered.
Of course, the degree of loss on each algorithm is
dependent on the split of Homes and Aways on the algorithm (varies by
algorithm) and then how the loss is made up by odds range. If the Aways
suffered a large loss because all short-priced Aways lost that month, my
algorithm will have avoided the damage. On the other hand, if the opposite is
true (as in this season), then my algorithms will struggle.
I could go on and on here and start looking at the split
by League but the data samples get very small. I will mention League Two Aways
though. This season, backing all League Two Aways blindly has made 10% profit
and therefore, my ratings have really capitalised on this factor this season.
As many of you will know, going into this season, most of my algorithms had
made a loss on League Two Aways over the last 3 seasons and therefore, anyone
who took a decision to drop League Two Aways have been hit hard by the underlying
results being so favourable in this league compared to other leagues. That’s just bad luck but it shows what can happen
in the short-term at this game.
Before I move onto the monthly review, I’ll try to sum up
my thoughts on what the above means for my own betting and for the service.
Prior to this season, I honestly believed that a season
was a long-time in football betting. I rate around 2,425 games a season on each
algorithm and therefore, surely that’s enough games to allow any trends to
level out and surely each season will give my ratings the opportunity to show
the edge they have? Now, I’m not so sure. I’ve never had a losing season (or
year) since I started betting on football but at the moment, it’s looking more
and more likely that this could be the first season where I don’t make a profit
on the football.
However, if I look at the last 4 seasons in total, there
isn’t much to worry about. If I had been offered 3 fantastic seasons and a
break-even season at the outset from the first 4 seasons, I’d have snapped it
up. Now I’ve had the first 3 seasons,
having a break-even season would be very disappointing but as I’ve come to
realise, I’m in this for the long haul. A break-even season hurts and given how
much I will have staked this season as well as the time and effort, to make
nothing will be painful but if anything, it makes me more determined for the
future.
Right, onto the monthly review.
Est Systems
The table above shows the results by value band and split
by Home/Away bets for algorithm 1. The
obvious thing to point out is the split by Homes and Aways. Homes had a good
month and made a profit of 7.1pts from 20 bets. 11 winners from 20 bets. Aways had a tough month with 8 winners from
32 bets and a loss of 2.5pts.
In terms of the value bands, <5% Aways had a nightmare
and lost 6.7pts from 16 bets. All the Home bands made a profit this month.
Again, looking at a month in isolation isn’t much use given the very small bet
number but I say that every month!
Overall, a profit of 8.8% from 52 bets is a decent month
for this algorithm.
Algorithm 2 didn’t have such a good month and overall,
made a profit of 0.4pts from 42 bets. Homes and Aways both made 0.2pts this
month, so a bit different from algorithm 1 and the general underlying results
this month.
The <5% Away bets was the best performing band for
Aways whereas the <5% band for Homes wasn’t great. The two highest bands for
Homes both had 100% records this month although there were no bets >25% and
no bets between 15%-20%.
This algorithm was the 2nd best algorithm
coming into the season but so far, it has found this season really tough.
Hopefully it can push on over the remainder of this season.
Here are the results for the Est systems this month:
Overall, a profit of 6.4pts from 185 bets. An ROI of
3.5%. Similar to previous months this season, the more selective the systems
were, the poorer the results became.
Systems 7 and 8 both had losing months which is
disappointing given system 6 had a winning month. System 22 did well though and
managed to improve on the returns on system 21.
Systems 6-21 and 6-22 both had good months (6-22 hit 4
winners from 8 for a 56% ROI) and therefore, going by previous seasons, you
would look for 7-21 to 8-22 to build on this. Unfortunately, as has happened
all season, the returns fall down a hole from system 7-21. 7-21 thru to 8-22
all had losing months.
Fed up saying this every month but this season is so
different to previous seasons. It’s a shame on systems 7-21 thru to 8-22 as
before this season, the ROI’s were exceptional on these systems after 3 live
seasons but there has definitely been a correction this season.
Overall, although the ratings had an OK month, the
systems haven’t capitalised on the ratings again. Systems 7-21 thru to 8-22
continue to disappoint as they have done all season and it will take a minor
miracle for these 4 systems to not suffer a loss this season. All 4 systems are
heavily in the red and have been all season.
New Systems
Here’s the results for algorithm 3:
I guess the first comment to make is that whilst the
other algorithms have been struggling all season, this algorithm had somehow
managed to achieve a profit in the first 4 months of the season in difficult
circumstances. However, it has taken a bit of a hit this month and has made a
loss of 8.1pts from 73 bets. Interestingly, it is the Homes causing the issue
and they made a loss of 6.9pts. Aways lost 1.2pts.
Drilling down into the Homes, we can see that the <5%
band did the damage with only 3 winners from 19 bets and a loss of 11.6pts. I
keep taking some comfort (not too much mind you given I’m ignoring these
ratings this season!) that when the lower value bets are losing, we can easily
escape the damage by just missing these bets out of our portfolio of bets.
The high value home bets were also 0 from 3 but it these
bets that have done exceptionally well so far this season and therefore, I’ll
give them a poor month now and again. Overall, a poor month for Homes but the
type of Homes on this algorithm are a little bit different (average odds are
2.99) and therefore, I think a bit of volatility is to be expected.
Here’s the results for algorithm 4
A really poor month for this algorithm although the low
value Aways bets were to blame. An overall loss of 13.7pts from 94 bets.
However, a loss of 18.7pts for <5% Away bets probably tells you all you need
to know about this month on this algorithm.
4 winners from 33 bets is shocking but strip these bets
out and this algorithm didn’t have a bad month. Actually, the <5% Home bets
lost 3.3pts too, so the low value bets performing poorly sum up the month on
this algorithm.
It’s disappointing that these bets have had a poor month
but as I said above, long-term, it’s no bad thing. If I can find a better way
to filter the bets to remove the worst bets (aside from using the system
filtering), then this can only benefit my betting and the service generally.
Homes made a profit of 3.5pts from 36 bets. An OK month
for Homes but no chance of undoing the damage done by the Aways.
Here’s the results for all the New Systems this month:
Given both rating algorithms lost 21.8pts in total, to be
posting an overall loss of 17.4pts from 351 bets is very pleasing. Not quite as
good as posting a profit of course but when the ratings have a nightmare month,
the systems can only do their best to minimise this loss and they did that well
this month.
Systems 32 and 33 had a storming month even though system
31 had a losing month. System 42 wasn’t quite as fortunate and seemed to make
things worse than system 41!
However, when you get onto the combined systems, you can
see 31-41 only suffered a small loss even though both individual systems had a
nightmare month and the top 4 combined systems all managed a decent profit.
(That’s how the Est Systems are supposed to work if they are reading this!)
If you look at the results before this month, it does
appear that we have seen something of a correction this month. The lower
systems (31 and 41) have been performing well all season but they struggled
this month whereas the higher combined systems have had a good month after
struggling all season!
Overall, a losing month and a disappointing month for the
New Systems but longer term and even this season, the results still stack up
well. These aren’t the worst systems this season, far from it!
Misc Systems
Overall, a profit of 18.8pts from 154 bets for a 12.2%
ROI. A really good month and I’m about to get very picky I suspect with my forthcoming comments
but I’m hard to please at times!
Looking at the split by system, 5 of the 6 systems
achieved a profit of 13%+ this month and therefore, it’s hard to be too
critical. However, given the way this season has gone, I don’t think I should
be surprised to see that STOZ is the system letting down this set of systems
this season and has been all season. Coming into the season, STOZ was the best
of these 6 systems but like the rest of my systems, this season doesn’t seem to
mirror previous seasons! An 8pt swing between STOZ and TOX/STOY and it’s very
annoying! All 3 systems hit 9 winners each, STOZ seemed to have 13 more bets
though!
Historically, it’s these additional bets that STOZ has
that separates this system from the other two (the two are 95% correlated) but
this season, it is these additional bets that are causing STOZ to lag behind
the other two systems.
My other moan this month about these systems is the split
by Home and Away bets. Historically, the Home bets on these systems have been
much better than the Away bets but this month, it’s been a horrible month for
home bets and a great month for Aways. A 6.7pt loss for Home bets and a profit
of 25.6pts for Away bets. Not only that, all 3 SG models made a loss on Homes
and these systems have the best homes from any of my system bets!
It really is a bit of a head scratcher if I’m honest and
for someone like me who has really enjoyed seeing the same trends repeated each
season, this season is proving a nightmare to understand. I’m sure the same is
true for others following and those who base staking plans and portfolios on
the live results, they’d be backing the wrong systems with the wrong staking
plan I suspect!
Overall, I can’t knock the returns this month and it’s
another step forward for 5 of the systems as they recover from the bad losses
in September. STOZ needs a boot up the backside!
Draw Systems
Another very solid month for these systems and my
confidence in these systems continue to grow and grow. I’ve been on a journey
with these systems whereby at the start of the season, I had more faith in
these systems than the Euro Systems (hard to not have after the mess the Euro
Systems made last year!) but after a very slow start and a lack of confidence,
as results have grown, my confidence has grown.
This month is the 5th live month and that’s 4 monthly
profits in a row. Overall, a profit of 39.7pts from 239 bets for an ROI of
16.6%.
The first draw algorithm (D1) made a loss of 6pts this
month but the second draw algorithm made 14pts profit. Pleasingly, the 6
combined systems all made profits again and these systems continue to impress.
I’ve said this before but I only follow 3 of the draw
systems in my overall portfolio but they have really saved my bacon this
season. Of course, I wish I followed more but it’s easy to be brave with
hindsight at this game and as I’ve said a few times this season, you make your
own luck at this game. If these systems had crashed and burned this season, I
would have regretted following any unproven systems in my portfolio but that’s
the chance I took. The fact I’ve been paid handsomely so far (still early days
this season!) is a little fortunate but I’m not complaining!
The next few months are big months for these systems and
if they can finish the season in line with current returns, I expect these will
become a much bigger part of the service next season.
As an aside, one thing I am considering for next season
is a set of draw systems for the Euro leagues. It would be a lot of work and
not sure whether I can fit it in without dropping other systems but I’ll have
some big decisions to make at the end of the season I think regarding the
future for my own betting and the service. I’m always looking for ways to
diversify further and I expect Euro Draw systems are probably an obvious place
to go.
In terms of other ideas for next season since I’m on that
topic, I think one issue this season has been the lack of Home bets in the UK
leagues and although they are traditionally not the most profitable bets my
ratings find, one option I could have would be to have some bespoke Home
systems. One issue with the way my algorithms work is that they really are
suited to Away bets generally and therefore, having some Home bets (including
some short prices) would maybe help smooth the returns and even if I could make
2%-3% ROI from Home bets at short odds, I’d be more than happy with that given
the ease of staking and the ease of odds availability.
Anyway, back to the review and another good month for the
draw systems.
Euro Systems
After a 100pt loss last month and me tearing the systems
apart in the monthly review and the blog results updates, they’ve bounced back
with a 104.1pts profit from 219 bets. Not only that, the filtering by system
worked like an absolute dream this month.
Before I get on to this month’s results, let’s recap
where we have been with the Euro systems before now. Last season, I built two
Euro rating algorithms across the 4 leagues (Italy, France, Spain and Germany).
Both algorithms were a disaster with system E1 losing 4.5% and system E6 losing
an amazing 9.3%. However, the filtering by systems seemed to work OK and it
seemed like a bit of a miracle that the top 3 combined systems made a profit.
I binned both these algorithms in the Summer, started
again and with the very same data, had a second go at building two algorithms.
So far this season, it was a similar story to last season whereby the ratings
weren’t doing well but by cross referring the algorithms, the higher combined
systems were again in profit somehow.
Roll on another month and boom, the Euro systems are now
back in the game and maybe (it’s a mighty big maybe!), these Euro ratings are
not as bad as I first feared. Those who remember the Euro systems from last
season will remember a number of false dawns with the Euro systems and being
honest, I didn’t have any confidence in the ratings and systems all last
season. I remember reading comments from people saying these Euro systems
looked OK when they were in profit but from what I could make out, they were
being kept afloat by some big priced away winners and overall, I didn’t care
too much for the systems.
I had that in mind when I built these new Euro ratings
last Summer and therefore, one of the things I tried to do was reduce the
average odds and switch the emphasis from Away bets to Home bets. The average
odds last season were much higher than this season as a result. However, with
the apparent Home bias in these Euro leagues (backing all Homes blindly
traditionally doesn’t lose too much), I figured my best chance of succeeding in
the Euro leagues was to have more home bets.
These new Euro systems have now been live for 4 months
and we have 3 months of profits and a really bad losing month. Thankfully, this
month wipes out last month completely and we’re back in profit for the season.
In terms of my thoughts on these systems, it’s still
early days. I have more confidence in these Euro systems than the same systems
last season (that’s not saying too much!) but compared to the other UK systems,
these Euro systems would be quite a long-way off I think.
I chose to follow 2 Euro systems this season in my
portfolio to give me some interest and combined with the Draw systems, these
systems have saved my bacon. Again, I wish I had followed more but I got burnt
a little last season from the Euro systems (would have been worse but I jumped
ship before season end!) and I wasn’t about to get burnt twice!
One thing I should mention about these Euro systems is
the number of draws they find. If you look at the AH returns, I could be wrong
but I don’t think I’ve had any set of systems produce such high AH returns in a
month. What this tells us is that with a few less draws and a few more wins,
this month would have been absolutely astronomical and therefore, the month was
maybe one of the best months any of my sets of systems have ever had! To create
100pts profit in a month is good but to also create 75pts for AH0 on all bets
is amazing. Last month, the systems lost 100pts but only lost 34pts for AH0
betting.
Overall, a great month for these systems and a solid
start to their season but a long way to go. These systems are a little behind
the UK systems and they haven’t reached the halfway point of their season yet.
Under/Over
Systems
Keeping this short. These systems have been teetering on
the edge of the cliff for the past year and a half and they toppled over the
cliff this month! A loss of 10.5pts from 44 bets.
These systems are already looking forward to their
retirement this Summer. I’m looking forward to not having to track the results
of the systems or spend time finding the bets each time either!
Overall
At a high level, a profit of 141.1pts from 1,192 bets. An
ROI of 11.8%.
In reality, as I said a few times on the results updates,
the actual results most people would have been achieving were nowhere near
these results and therefore, it was a tough month. To be fair, when the Euro
systems lost 100pts last month, that brought down the returns for that month,
so they have boosted the returns this month!
It’s difficult to see how you can make a profit this
month, even with a well diversified portfolio. To make a profit, you needed to
be following as many Draw and Euro bets as possible and as I said on a recent
results post, if that was your strategy this season, you were following the
wrong systems!
The season is going to be remembered (if that’s the right
word?) for what has happened to the UK combined systems I suspect. We’re now
past the halfway mark and systems such as 21, 7-21 thru to 8-22, 33-41, 33-42
and STOZ are all loss making for the season. As many reading this will be
aware, before this season, these systems had 1,2 or 3 solid seasons behind them
and had achieved very good returns, so it’s disappointing they’ve all struggled
so far this season.
In reality, some of it will be due to the fact the
conditions have been tougher this season as outlined in the beginning of this
post, some of it will be due to a little bit of luck not going our way (never
had so many big bets lose 2 goal leads) and the rest of it will be down to the
systems just not having as good as a season as the last 3 seasons. Poor seasons
happen and my systems are no different to any other systems with an edge but if
you get a bad mix of these 3 things as some of the systems have had this
season, it can lead to a really poor set of results.
Of course, some following the service this season are
possibly sitting with a portfolio including a number of the systems that have
struggled the most and therefore, they must be wondering what they have done
wrong this season. Have they done
anything wrong?
I’ll leave you with that last thought and for my next
blog post, I’m going to touch on a few issues people have had this season
following the service and try to respond to some fair criticisms thrown my way
recently.
