moeee, ive got a prizemoney system where it goes from LOTof 12% to a POT of 31% ..... A HUGE turnaround for a simple fiter of just looking at Saturday Class .. Many would nod their head in agreement. Party's systems picked up the importance of this filter too. Incidentally, a little tinker with selected Api rating and days since last start (all logical) got this beaut to 71%. It has 12 rules but they're all compatible with each other and with one main rule "A MYTH BUSTER".
