About 4 years ago I did this in 0:04.77, then Rocky beat it with 0:04.71. We both made the mistake of curving in the wrong direction at the very start which carries less east momentum into the hallway, so that was some low-hanging fruit to fix up and is where most of the time saved comes from.

I was 3 frames ahead of Rocky at the linedef opening the exit switch sector and managed to squeeze another one out by also getting a slightly better curve back into the staircase hallway. That kind of movement sucks to work on, because as you change your movement before running down onto stairs, it changes which frames you subsequently hit the stairs on so its really frustrating to iteratively test. Took an annoyingly long time to do, I was a couple of units away from the exit switch for a while but got it eventually.

I got motivated to look at this again after 4shock and jOY have been going at attempts as part of Andreas Final Doom demo month contest.
