I started playing at those stakes and I have double your 3bet%, higher cbet% WITH a higher cbet success rate and my red line goes up.
I can only predict so much how you play but really at these stakes there are glaring mistakes these guys have. 3betting regs a ton is very profitable as most fold way too much. The cbet stuff is really working on flop texture stuff.
I don't really know what to tell you other than if you shoot me a video or something I'll be more than happy to look over it.
