I really think ppl way over-estimate rakeback etc. You can make SO MUCH MORE than rakeback if you improve your play over that same volume. Not to mention you'd still be getting rakeback, even if the volume is cut by 30% or so.

A lot of people playing mass volume, their winrate might drop significantly from like 2 or 3 bb/100 down to 1 bb/100 or sometimes even almost break even. If you're starting at a winrate so low at high volume, it's not unreasonable to assume that cutting volume by like 30% could improve your winrate by like 50% or more.

ie: cut volume by 30% = (.7), but improve winrate by 50% (1.5) -> 0.7*1.5 = 1.05 (so NET GAIN) despite lower volume and lower rakeback proportionally.

Note this 50% improved winrate is just me assuming that you'll just play better when you can focus more on less tables. This doesn't even account for actually being able to improve over time due to this focus.
