I had a few small mistakes in my old Dan WR, but this time it was basically flawless. The biggest difference was skipping Focus/Red Focus cheese strats, and faster corner carry. Turns out dashing is generally faster than using HK Dankyaku (although neutral jump buttons are harder to time, and on 24 it requires a microwalk afterward).

On Trial 23 you can actually start with only 4 dashes, so that's pretty much my only remaining time save. I'd be surprised if anyone could save 2 seconds unless there's a consistent way to make U2 drop after one hit.
