PT is a little misleading: if roulette was the game then we’d all be losers long term, but a ‘PT DB’ of the game would show a good proportion of winners after a reasonable length of term. I wouldn’t have though so low as 8%, maybe 1 in 7, but I can see that it is credible. The other moot point is there is not a 1 in 12 chance your opponent in a pot is a winner, unfortunately it’s much higher. The reason for this is that winners play a lot more hands/ year than losers. This is probably why ‘it feels’ that 1 in 12 is so low, since it is extremely rare not to find a winning plaer at your table and so our perception is one of much higher.
