Didn't think you'd be able to back up your assertions mattio ..... Your system leaving out Melb and Syd is similar to targetting selected racecourses just because there was some success in the past, regardless of the fact it's illogical.

My systems, granted they have few bets, are based on logic. Yes, I do have several filters that can be applied to any logical system and guaranteed to improve the POT. There have been many systems posted on here claiming POT's of 50% to 100% which when tested for logic cannot possibly stand the test of time, and, when tested on an accurate database over a decent trial period show a loss, not the POT claimed. One prolific poster of systems must have a very friendly database that only shows up POT no matter what rubbish is entered.

My systems are logical and also shy away from what is traditionally sought after by 99% of punters. You can backfit anything mattio but without logic it wont be successful.

Hope this has been of some help to you mattio, and your new found buddy moeee.
