Creating Betting Systems III

Today we have a regular weekly catch up with Malcolm Pett of http://greyhorsebot.com

In the first two articles we looked at why I like systems and how I came up with the ideas.

In this final part I want to share with you some other things I have learned along the way which may help you when designing your own.

First of all it easy to get caught up in an idea…

Often you pursue an idea and start looking for ways to make it more profitable by filtering out more and more races until you end up with something that resembles the system you want.

I call this “Stacking and Racking” filters.

The problem is, everytime you add one filter you affect another and the more you “stack and Rack” the more likely it is that you have missed a better more profitable angle.

When you add a filter you should step back and see how that one filter works on its own against the original idea.

Secondly sample size is really important.


If you do a search initially on hurdle races you could have a massive sample size which will give you a good indication of the statistics.

Sometime during your research you may see that filtering out a certain element like an age group or last time out result may appear to improve the system.

But you have to be aware that a small sample size could be misleading and may not give you a very accurate statistic.

I don’t normally use a filter unless I have s sample size of at least 100 and really prefer much higher.

Finally you may want to stick to one race type. Hurdle, Chase, AW, NHF and Flat are all different types of racing.

It isn’t very often that you find a system that works well on one race type will also work just as well on another.

Even when you do…you will often see different win/loss trends across the race types.

If you analyse them individually you will probably find filters that work better on one than they do on others.

To finish off this series of articles here are some other things you may want to consider if you decide to develop your own systems.

Be aware of trends. All weather systems are a classic when it comes to trends.

Something that appears to have worked for the last 6 months or maybe even a year suddenly doesn’t.


Many archives don’t include Non Runners. This is not a big problem until you realise that on the day you may have selected that NR and not have been aware of it not running.

I find this really important when looking at runners ranked by a Rating Systems.



If you run the ratings leaving out NR’s you will of course get different selections than if you left them in. Don’t forget you don’t always here about NR’s until after the off. 


Don’t forget when you look at a system you are seeing the results based on SP or BSP and without you adding money into the market. 
You will only see how well it performs when you start using it.


Paper Test first always…Then small stakes. 

Any money into a market effects the price no matter how little. I use what I call “Price Pressure” to see what effect lowering the Average Winning Odds will have on a system.


Always be aware of your Strike Rate and Average winning odds. Look out for trends of either falling. But be aware short term trends can give false impressions.

You need to look at your system month by month to get an idea of how it performs and always create a graph. There is nothing like a visual display to show you how a system has performed.


Watch out for the “One big winner trap”. You often find a collection of data looks really profitable only to find it is actually just one or two big winners that actually created all the profit.


Finally please remember this…

I am a big believer in betting systems but I also realise that the biggest flaw with them is that you are using the past to predict the future.

The big advantage of creating your own systems is that you can tailor them to suit your own style of betting and instead of creating one. You can create many “nano” type systems that look at one particular type of racing.

Thank you as always for reading I really do appreciate it.

Windsor Draw Part Deux

Following on from Tuesday's article I'm looking some more at the effects of the draw at Windsor.

To recap we found that stall 9 was profitable when 8 or 9 ran (8 because of non runners).

My next step is to look at how the differing distances perform for stall 9 and then I'll try and expand things out for the highest stall number in any race.

The course at Windsor has a lot of bends, with the 1 mile races running a figure 8.

The only start that is right on a bend is the 1m 3f.

Here are the numbers for the last 10 years…

What we can see here is that our Stall 9 is profitable at all distances except 1m 3f, I wouldnt be surprised if stall 1 performed better at that distance.

Next I have restricted my analysis to distances of 1m2f or less.

Here is the data for 5 runner races…

I don't have the time to go all the way to 20 runners or more, so let's discuss what we have.

Each table shows strong profit at one of the high stall numbers, the data is obviously skewed because sometimes there will be a stall allocated that is higher then the number that ran, because if say 12 are declared then stalls will be allocated upto stall 12, but if 2 then withdraw then the race is shown as a 10 runner race.

I think there is some sort of advantage here when drawn highest over any distance at Windsor other than 1 mile 3 furlong.

I cant get the exact data that I need, which would be performance of highest drawn horse in the race.

Personally I will be looking through the card at Windsor on Saturday and following the highest drawn horse.

If anybody reading can tell me how to get the data I need, or of anybody would like to volunteer to go through an manually research the 10 meetings that Windsor has had this year then I'd be pleased to hear from you.

Fit and Fancied Done For You!

On the last day of my guest spot here, I just want to sum up what's been said.

Firstly, I think we have come accross a phenomena, a relatively new trend, which the general betting public and the bookies have yet to catch onto. This is the growing ability of trainers to recuperate their horses in time for a winning run within a short period of time.

This is probably because of advances pioneered by other trainers, Martin Pipe in particular, such as swimming facilites, physio, all weather gallops, etc, and other things I wouldn't pretend to understand as i have no experience of training horses.

This is just my educated guess. All i know is an awful lot more try and an awful lot more succeed these days, and that is what is important for us from a betting point of view.

I have shown you how we devised two systems, one for the jumps, Fit and Fancied Jumpers, and another for the all-weather, The All Weather System. Both of these use, as their basis, knowledge of this relatively new phenomena.

The interesting thing about the Fit and Fancied Jumpers system is that it does so much better in hurdle races with one outstanding exception – handicap chases. As I have openly acknowledged, I am no horse expert. My forte is stats and what I have been able to learn about probability. But, and again this is an educated guess, I think 2 miles over fences must take more out of a horse than the same over hurdles and therefore a longer recovery time is necessary. In which case, how do we explain the success with the handicap chasers?

My theory, as I said in the ebook, is that these are the type of races where trainers are trying to land a gamble and therefore maybe the horse wasn't given too hard a race the time before.

If it won, maybe it won in a grade well below what it is capable of winning in. In short, it didnt have too hard a race last time and therefore didn't need much time to get over its exertions.

This may explain why the system doesn't do as well with horses in NOVICE handicap chases. Horses running in these are not so experienced and may take more out of themselves than is necessary by running too keen, jumping too extravagantly etc.

The All Weather System is completely straightforward and gave us 5/1 SP winner, SCRIBE, yesterday.

Now, the question is: having gained this knowledge, what are you going to do with it?

I am afraid that, in all likelihood, the answer for many readers is, nothing.

A few disciplined souls will be able to ignore life's distractions and will scour the Racing post each night, (the info for both systems is online by 6.30 – 7 each night), for the system selections.

They will be able to back the selections at early prices on the exchanges or at Best Odds Guaranteed, (BOG) the next morning – thus gaining a further advantage. But the vast majority will not put this new knowledge to use whilst others will try to use it but not always come up with the correct selections.

This series of articles has aroused some interest and a few people have emailed us to point out that they may not have the time or the discipline to look for the selections themselves.

Also there has been some inevitable mistakes in the selection process so that some have thanked us for winners that weren't selections, while others have complained about losers that weren't selections!

This has led some to ask whether we have considered providing an email service. The answer is, we already do.

We send an email each night – whether there are selections or not – between 7 – 8. Where there are selections you get the race and the name of the horse and we recommend backing them all at BOG.

The cost is £7.95 per month for each system, fully inclusive, ie, no taxes on top.

However, we have been persuaded by Dave and the Daily Punt team to make a special one-off offer to Daily Punt readers, for today only, of an email service for BOTH systems for just £12.95 per month.

You will surely pay for that out of the ability to get on at early prices. Click Here.

Those who take advantage of this one day offer will also receive a FREE copy of our ebook BACK TO THE FUTURE, which shows you how to back your selections in a novel way which changes around half your losers into non runners!

If you are interested in this option click here to secure your place now.

I hope you have enjoyed this series and will put what you have learned to good use.

Good luck in your future betting.

All the best,
John Cutts
