Expectations for 8-tabling...

[Jurollo]

So I am a long term winner on 2/4 and have just got a 2nd 2001FP. I get 28% rakeback and average 205 hands per hour right now. What kind of expectation can I expect when I begin 8-tabling? Lower VPIP (folding more borderline calls to focus on other tables)? Lower BB/100? I am assuming that by putting in 20 true hours a week, approx 80 hours per month I can easily make the following...

28% rakeback - $980
Table profits - $1900-$2600 (1.5-2BB/100) ... (Big Bet)

= $2800-$3700/mo

Looking good to people? Any tips before I begin the 8-table grind?
