You probably need to set/nutcamp more
Quite possibly. Is 24/15 too aggro for low stakes? That's something I've been wondering.

and get away from TPTK/GK and 2 pair more often
Honestly, I really don't have a problem getting away from TP. Well, except for times like today when I had already eaten such a huge shit sandwich that I pushed my TPTK out of pure frustration. Ok, there's that, but normally, I really don't do it--I will almost always lay down TPTK I Iseven to a minraise.

3 and 4 tabling you might not be getting the reads you should either.
Without question, but I usually one table.

And post some (losing) hands.
I should and will do that more. Meanwhile, are there any huge leaks that can be identified by just looking at the numbers?
