6. What is a good ROI/ITM%/FT%?
Difficult question to answer, generally many have said that any positive ROI is a good one, 100 is solid. As for ITM, anything over 10% is good, and MTT guru Sirio has said his records haven’t shown any player above 20% with a decent sample size (this is for online tournaments with fast structures, deeper stacks and slower levels should allow a skilled player to break that cap).
