Not too many have shared their best filters Maark, have they? If you're still around my best advice is to look where no-one else is looking. New punters come along all the time and currently we have sophisticated ratings to help pick the winners (the fav S/R hasn't changed in 100's of years tho'), years ago these same ratings were to be found in the Sporting Globe tipsters columns, they went under a different format. Today's is more exciting, but no more profitable. So we still keep looking at the usual good form, newbies come along and join in and they look for good form, a tweak here and a tweak there and they've nearly got it!! But they haven't and never will, çoz the odds will get you all the time when you're looking for winners using similar methods that everyone else does.

Look where no one else is looking and test (don't backfit).

good luck.
