Ok, I will. Few non blackjack players like you know this, but in a normal off the top of shuffle blackjack game with a house edge of roughly .5%, a player will win 43% of hands, loses 49% and push 8% (roughly). So Even when the counts goes positive to say true count +4, playing with about a 2% advantage, those percentages only move slightly. The player will win just slightly more and most the difference is just slightly more blackjacks @ 150% payoff (will also fair slightly better with double downs, but the blackjack are the main thing). That is all it takes to flip the game from a slight casino advantage to slight player advantage.
So at no time will a player be winning more than 45% of rounds longterm. At NO advantage achievable from card counting. So for someone to say they win 60% of their max bets is...well bonkers. Simply not the way it works.
