ok, I do see there is big difference between party clearing rate vs. pokerstar. For example .25/.5 NL 6 max
party $12.6/hour
ps $1.2/hour [img]/images/graemlins/tongue.gif[/img]

This doesn't necessarily mean anything. You may not have played enough hands for it to be a good estimate of your true win rate. I found the NL 100 games to be about the same on both sites.
From my PT stats I have found an increase in my hourly rate per table by $2.90. I think this is normal. I would say it increases your hourly rate as little as $2 and as much as $4 per table.
