Now, I don't want to jump to any conclusions. I've only been playing about six hours total 6 tabling $1/$2. However, I seem to be making many more mistakes 6 tabling than when I was 4 tabling.
I feel that my concentration is pulled away from the game when I add any more tables after 4. 4 tables seems to be my limit. That is rather upsetting, but I think, for now, I am going to stick with 4 tables.
Maybe once I get a 2nd monitor and can see the tables in full size (rather than using the resizable tables feature to shrink the tables down to where I can have 6 tables) I will try and 6 table again.
Maybe if I get bored this summer I'll attempt to six table again. We shall see.
