I am keen to explore the relationship between BPSP and ISP. On the Betfair Timeform results site http://form.horseracing.betfair.com/hor ... B-Car/1515
the information is displayed with a % advantage you gain by backing at BFSP. It is clear from this that there are several strategies that can be applied to take advantage of the gaps between what the bookmaker and Betfair prices are at the start of a race. What I am interested in doing is adding a column to a spreadsheet that mirrors this % as displayed by the Timeform site. I cannot work out how to to accurately replicate this number. I have spent ages on this, but I have got blinded by the numbers, I need fresh eyes on it.
Can anyone work it out?

The % displayed is after commission at 5% is deducted. So if the BFSP price was 2.1 and the industry SP was 2 it would show an advantage of 4-5% or so.
Without discouraging you from your analysis, as you don't know what the BFSP will be until the race is off and you don't know what the industry SP will be until the off, I'm not sure where you are going to find any profitable strategies.

I have found 2 that work. I know how to automate it too.
The missing piece is the exact calculation. That looks lik it works.
I swear I tried that right at the start . Just shows you how a simple mistake can cloud your results.
Cheers for that.
These results sheets are a rich source of ideas. have a look at see what I mean.
