[QUOTE=Barny]Vortech, I'm glad you're posting. I like a debate on theory. I don't see anything wrong with "backfitting", whatever it's called, massaging filters to suit an outcome ..... because if it's over a long enough period then the correct / decent / profitable filters will eventually be isolated.


If you have a system which shows a profit over 12 years of the following

Horses with TAB 2, 4 and 7
Brisbane races over 1050m
Saturday only
Good track
Field size of 14

Over 12 years showed a profit of 53%POT

Would this continue?
