um if you are calculating your ROI from sharkscope
i'd be very careful. I'm 99% sure that the sharkscope ROI is absolute garbage. For example, i know a guy who has 1 1/2 times the amount of games as me, the same average stakes but only 1/3 the profit i have. His ROI however is higher. I have even seen losing players with a positive ROI so try to figure that out :S I think sharkscope has my ROI at 29%, but i have a 1.7$ average profit on a 4$ average stake so that would be somewhere from 38-48%. The guy i know has about 70$ profit on 200 games @ 4$ average and has a ROI of 40 something :S.
However, as to your question, it really depends. Did you get a lucky cash in an MTT? You have very small sample sizes so an odd run is likely to skew your actual rate. All those numbers are perfectly fine but just keep playing and figure out what is working. You might want to try different SnGs...45 is obviously different from STT and 6 max turbos are alot different from 9 player non-turbos. So just experiment and see what works.
