I'm assuming you're a 6-33 buyin player, correct me if I'm wrong.

20-40 buyins are most common for this buyin level. More or less isn't unheard of.

A few hundred games is a good sample, 300-500. If you're a marginal winner or loser then a lot more. (Also note that learning and improving your game will negate a lot of previous samples).

10% ROI is a good number to shoot for at 6-33 levels. You can get over 20% but 10% is good. Very dependent on learning ability, tilt control and variance, and your real winrate can and will change often.

These are very general questions, for more specific answers use the search function and read the FAQ.

I think I'm going to bookmark this thread as reference for future threads (I know there will be more) unless anybody has a problem with my answers.
