With no rake, 3BB/hr+ is definitely possible, but with a standard rake I think it is likely that 2BB/hr is closer to the maximum win rate for a good but not great player. One of the main reasons for this is that the worse your opponents play, the fewer hands/hr you get, especially in a game like Omaha8. At 20 hands an hour, you have to average almost a big bet per hand you play voluntarily which is unlikely. However with no rake (which will cost you $6-$12/hr), 3BB/hr or slightly more is probably achievable in a game like this. It is also possible if the game is frequently shorthanded. With a standard max $3-$4 rake, I doubt that anyone can earn 3BB/hr in the long run. Note that this does not necessarily disagree with your statistics as the 95% confidence interval for your win rate is:

$12.01 - $28.43

I think stud8 is a much better game to play against horrible opponents. It is as easy to screw up as omaha8 for the bad players, but you get more information. Also, it is tougher to back into hands.

Good job.
