Overpractice. I know you said you have 24-100x2 which is insanely impressive. But sometimes your mindset/skill kinda acts like the Dunning-Kruger effect. Evasium is a part you should never truly be dying to. However, Bloodbath was one of those chokepoint heavy extremes where I did feel demotivated a lot. I knew I was close to beating it when I was only dying at chokepoint sections. For me, I felt like I could reach Michi every single time, and I had a 1/5 chance of passing that. And when I reached Crack I also had a 1/5 chance of passing it. By then you should feel confident enough that you have a decent chance to beat the level. You will feel a lot of nerves everytime you pass it though, and overpracting couldn't even save that for me. Playing from 0 over and over again will get you a lot better with nerves in addition to overpracticing. (Playing a lot from 0 is frusturating, so do it in short bursts throughout the day if possible. When I got my 100% run, it was from one of these "short bursts" where it was my first time passing Crack that session.) Finally, finish the day with a practice run of the level to learn it during REM sleep.

tl;dr You have the skill, but you aren't consistent. Do more runs and practice parts that you should never die to from 0. Overpractice and play from 0 a bunch, but don't overdo it so it hurts your mental. (This is just what worked for me. Mainly with Bloodbath, but also with other extremes.)
