I dunno if this will help you, but here is something I found useful.
When it gets like this, I will only play a single table. I will have the equity calculator from PT4 open, and when I am in a hand, I will take my time, and put the stats into the equity calculator. If you click on "sel" you can select ranges for the other players.
From that I will get a pretty good estimate of my %age to win at each stage. I can calculate the pot odds
and compare to the odds to win and make a judgement call to fold.
It has helped me to build fold discipline.
I am playing much calmer now, and more patient. I am better at folding bad and marginal hands, and this method also helps me work out when I am ahead and by how much, and therefore my bet sizing is also improving. When I play two or three tables, I can't use this but my insight is getting better.
Hope you find it useful.
