I didn't realise peoples databases wouldn't have beaten lengths. I thought this would be one of the standard and perhaps most important figures.

Regarding average prizemoney vs strike rate, that is probably a fair point. I think this may be why it worked better on country racing, as there is probably less horses with the top strike rate running in races above their class.

As for the horses who haven't won anything for a while this is probably true, but the beaten by less than 4 lengths indicates they may not be totally past it. Maybe add a win or placing rule in their last five starts, barring the last start.

Anyway would like to see the raw results before i begin tweaking.

Thanks again for you input.
