I'm currently on a 13-14k downer, which is about 35-40 buyins.

I don't think I get particularly tilted anymore. I don't go into crazy spew mode generally, but I do potentially make "how can they have it again" calls, which I suppose is some form of tilt.

It's also hard to keep a good perspective on what is or is not a good call. Right now everytime I triple barrel and get jammed on (when I have a big hand) and I call they alway shave the nuts. It comes to the point where it feels like I literally should just b/f my entire non-nut range. This is in complete contrast to my GTO studying which suggests I should be calling like 30-40% of my betting range in that spot. That's one thing that is hard to balance. It's hard to balance trying to study and implement GTO through a downswing, that's for sure.

I'm just rambling now haha, but it's def a good thing if you feel like you maintained a level head through a downswing. It def can't be bad!
