WHY? 10,000 bets can produce a POT of 1% and the next 10,000 could produce a loss on turnover of 2%. If you are dealing with such small margins that is no aberation. It means that after 20,000 bets there is a loss on turnover, NOT a profit. But what smart staking can do is turn a small loss on level stakes turnover into a profit. Your theories say it cannot be done without wiping you out. lol But betting is NOT theory, it is practise.
