that really depends. some people are cash game sharks and some are tourney sharks. if someone is 20%-30% roi in tourneys i dont really consider that bad. if you look someone up and they are 458% roi then most likely they have only played a few tourneys and the roi isnt really very accurate. just my opinion. honestly if a guy cashes for a profit 1/3-1/5 of the tourneys he plays imma consider that person a shark n tough to beat
