SNG player will make an ROI of 15%
Limit player makes 1.5 BB/100
NL player i don't know, maybe 6bb/100 at the higher stakes?

Average 1.5 SNG per hour.
NL/Limit table plays 100 hands per hour.

to make 10$ per hour per table, you can play:
-50$ SNG
-3/6 Limit
-1/2 NL ?

Above poster claims to make 3BB/100 or per hour at 10/20 Limit. Seems phenomenal to me. 2-3Bb is normal at the micro stakes, not at 10/20.
