hi michaelg
a semi-professional punting mate of mine uses the don scott ratings this way hits the clear button on (form)( condition)(consistency)(barrier position)(jockey) then hits submit leaving the market at 90% only considers horses priced at less than <$11.0 in the market and only considers races where their are no more than 4 chances at <$11.0 so you are effectively looking at the top =4 (best recent run) only so a straight don scott weight rating as i have no back data maybe wesmip1 or lomaca could investigate in all fairness this may worsen the profits on your system i have absolutely no idea food for thought i guess as i said may not work at all he only bets when the minimum price is $3.0> and only considers races where all horses have had at least 2 starts> bets melb sydney metro only
cheers
