STEVE, my 2 cents worth,...... I have a daily up-dated POT column , i.e. since the start of the system till NOW. To me that is the acid test because a system made 50% POT 3 years ago but is now 50% down so far this year is irrelavent (in my opinion) as it should be an on-going thing, I mean where do you draw the line 100 bets, 10,000 bets 500,000 bets?? where?

Kind of like when we hear that 30% of favs win ( near enough) we are talking about including all races since 1800 and something, if we started analysing that you could pick out "sections" that say something entirely different!
