I'm curious if there are any widely-accepted rules of thumb for what a good player's ROI would be in blackjack tournament. I'm aware that a variety of factors will obviously impact ROI, so I'm just looking to assume a standard lineup of players for whatever stake level you're familiar with, and no money added along with no rake. Something akin to the 2 big bets/hr rule for limit hold em, or the 25% figure for poker tournaments. I'm trying to gauge if it's worthwhile playing the mid/low-level tournaments in my local area (South Dakota, so I doubt I'd be infringing on anyone's territory). Thanks a lot!
