I find that my winrate goes down directly in relation to how many tables I play. This is also very true of my redline. My redline goes up when I play a table or two, but dramatically goes down once I hit 6+ tables. I actually make more money with less tables. Rakeback is more with volume, but I find that it's not worth it.

Concentrating on decisions, and not being a multi-tabling bot is way better in all shapes and forms. Playing better poker makes you a better player, and not more hands playing sub-par poker.

That's what I learned this month. Taking the time to concentrate on each action, and planning out streets against specific villain. This is extremely hard to do multi-tabling and watching TV, etc.. at the same time.

That being sad, some players/grinders are lazy and don't put in as much time at the tables as we would like by the end of the month. I think there is a distinct difference between time at the tables, and how many tables/hands are being played.
