We have typing enjoyers here? HELL YEAG! It's been a while since I practiced but I was somewhere between 90-105 WPM iirc. Honestly I don't really want to get much better with QWERTY, maybe 120 WPM would be a good goal, but I think it's much better to learn an alternate layout, there are a bunch of layouts that are very new and have better ergonomics and stats once you learn it. I was learning a NRTS-HAEI layout called Lucens which is a custom version of Gallium iirc that I found on the Alt Keyboard Layouts Discord server. I still have it setup on my PC with Kanata (layout customizer software) but it has been a while since I used it.

I've always been jelly of people who can do perfect touch typing with all 10 fingers.

You can learn! It's not that hard to learn proper touch typing, I remember having kinda the same type of typing you describe and years ago just decided to properly learn it, tho I usually only use my left thumb, not the right one and it's something I have to get better at.
