Here's a nice little optimization for the noisy floors after you get captured. Messed around with this noise mechanic in the middle of my current replay. I think the game is simply tracking whether you are holding the walk button in the zone of the noisy floor, rather than Kaim's speed. This ought to save a few seconds over walking, but I didn't time it.

Played on Xbox Series X, NTSC-U

I used to do this on my playthroughs. Good to see it documented though.
