Been playing $10 Jackpot SNGs on ACR, currently have 180 buy ins. Could someone give an idea of bankroll for these types of games/when to move up to $25 SNG (lowest next level)? I know 180 buyins is within range, but would like some more elaboration on it! Also, how many games for a somewhat accurate ROI/what is a good ROI?

Thanks!
