is this bankroll logic correct?

StankCooter

if my roi is 10% , and im grinding 1.50$ 9handed turbo sit n goes, in the long run i will only be making 15 cents per game i play .At that rate i should expect a profit of about 15$ after playing 100 games. however due to variance i should maybe increase the field size to 200 - 300 games and expect to be around 30-45 $ more in my bank roll.?

trigs

if you're talking about increasing the number of tables you play at one time, it's normal for your ROI to drop.

even 300 games is statistically insignificant

Even STT can have horrid downswings of 20+ buy-ins once every 500 games for a winning player

so if im grinding up to around 30 $ profit after about 175 games but i hit a cold streak and lose almost all my profit does that mean im not winning enough to beat the cold streaks? or i just got unlucky by hitting the cold cards when i was only up a bit of profit?

compuease

I think what others are telling you is the number of games you have played is NOT enough to determine whether or not you are a winning player. If you are a winning player a bad streak could still wipe out all of your bankroll unless it is at an appropriate level for the stakes you are playing. If you are a losing player (approx 90% of players) no amount of bankroll will keep you from going broke..
