Thanks for the reply.
Yeah I agree w/ what you say about iso-ing vs calling, I do tend to limp behind more with those hands, although, it does feel a little wrong! My high pfr is a lot to do with how much I steal though.
I keep my 3betting range pretty polarised, there's never really a situation where idk what i'm doing to a 4bet, I don't think 10% is too high otb though, most of the hands i use are like off suits aces and other stuff w/ blockers that I can't call with.
