Hi Darky,
Taken me a while to get back.Thanks for the idea you mentioned seems worth looking at.

I am playing around with an idea I got off this very forum a while back in one of the old threads. It involves adding up the last 5 SP figures and then dividing by 5 for an average. Look at horses which have been bet down to less than their average this start. I have been only using the las 3 SP's as I use a free Formguide. It certainly points you in the direction of a few good chances but needs more filters such as days to last start, beaten lengths etc, not even sure. Horses backing up after 7 days seem to do well. Early days yet and I'm not sure if it's a goer long term. I'm looking at midweek races so far.

Another question.

In the "Hypothetical Handicap" a horse A's last three SP figures are 4/1 4/1 and 4/1 total 12 and an average of 4

Horse B's are also 4/1 4/1 and 4/1...BUT horse A's runs were all in fields of 12 and horse B's runs were all in fields of 8

Does this mean that horse A's 4/1 is better than horse B's 4/1 as horse A ran in bigger fields or are the size of the fields already factored into the price equation?
In other words do you have to make an adjustment for field size and if so, how do you do it?........or am I just wasting my time ha ha!!
