What Should our ITM % be for Poker Tournaments? Although 15-20% is a commonly cited figure, the truth is that it entirely depends on the type of tournaments we are playing along with the number of entries. For example, if we had 20% ITM when playing heads up sit and goes we would clearly be losing overall.
You don't need a massive sample to realise your edge when the field sizes are 100-300. This is one of the reasons why Super High Roller tournaments, which tend to have 30-50 runners, thrive despite being made up of tough regulars, you might only need a sample of 500 MTTs.
