14th November 2007 2007
I spent the evening at Betfair last night talking about
some of the new technology they will be launching soon.
They are going
to start offering an SP (starting price) which will be worked out just at the
off. So very much like you can do with the bookies, very soon you will be able
to just ask for Betfairs SP. They feel that the Betfair SP will be more
profitable than the bookies SP even after their 5% and the other difference is
that you can have an SP on the lay side as well, but you will have to stipulate
your maximum liability because you will not know the final price you will be
getting until the off.
I will tell you more next week but I just thought
you would be interested to know what may be coming next.
One other new
thing I have been meaning to talk to you about is that you can now bet on the
place market "in running".
Have you tried this market?
love to hear from anyone who has tried betting on this market and what
strategies you may be using.

How Accurate Are Your Estimates?
So, you have devised a system for laying or backing horses, dogs, football
teams etc. From your testing, you have determined that it is profitable. But,
you haven't started to use it in anger yet - you are still testing it. Before
you start using it to place real money on the selections generated by your
system, you need to know two things:
1. How much more data do you need
2. How confident should you be in your system?
let's answer these questions.
Let's say that you have tested your
system on a number of races or matches and have measured its strike
If we take the square root of the number of matches or races and
divide it into 100, it will give us the accuracy of the strike rate.
Does this help us, if so, how, or is it a complete and utter waste of time and
The answer is yes - it will help us and no - it isn't a waste
It will provide us with a mathematical
measurement of how much confidence we can place in the accuracy of the system's
strike rate - as measured by your testing.
To make things a little
clearer, let's take an actual example.
Let's say that you have tested
your system on 100 races or matches and have found that the strike is
If we take the square root of 100 (the number of matches or
races), we get 10. If we divide 10 into 100, we get 10. Therefore, the accuracy
of our strike rate (80%) is 10%. In other words, the long-term strike rate is
actually 80% +/- 10%. So, the strike rate could be as low as 80% - 10% and
could be as high as 80% + 10%. Therefore, the long-term strike rate of the
system is somewhere between 70% and 90%.
As you can see, the more races
or matches that you test your system on, the more accurate your actual strike
Now let's say that you have tested your system on 900 races or
matches and have found that the strike is still 80%.
If we take the
square root of 900 (the number of matches or races), we get 30. If we divide 30
into 100, we get 3.33. Therefore, the accuracy of your strike rate (80%) is
3.33%. In other words, the long-term strike rate is actually 80% +/- 3.33%. So,
the strike rate could be as low as 80% - 3.33% and could be as high as 80% +
3.33%. Therefore, the long-term strike rate of the system is somewhere between
76.67% and 83.33%.
If a strike rate of 76.67% (the lowest estimated
strike rate) is high enough to produce a profit, you can confidently start
using your system to place actual bets.
If a strike rate of 76.67% (the
lowest estimated strike rate) is NOT high enough to produce a profit, you have
1. Collect more data.
2. Put your system in the
Note that I showed you how to determine if a system is profitable
in my previous article.
So, you can now see how to determine how accurate the calculated strike rate of
your system is and whether it is reasonable to use your system in anger by
simply using the number of races or matches that you have tested your system

it is still in testing. However results have been very positive so far, it has
