agreed - intentional or not some folks need a lot of work on their win loss scoring. i think they tend to throw out losses and throw in wins - in other words they are unintentionally shading the count because they want to find something that works so badly.
ive been around this close to 40 yrs. i ve seen a lot of "systems" but none that work over more than a short period. eveything pretty much seems to find its way back to 50% over the long haul.
the only thing that works is putting in the time to get the game info and working the stats.
