I found a trick on an awakening that lets you return to a checkpoint in an unloaded part of the map allowing you to just navigate some left over invisible collision to just jump to the elevator. This glitch is very easy to reproduce. I believe it can be done with out the dash at the start of the level haven't tried. I got a 31.280 run with it after a short bit of practice The video explains it a bit better in its description. I didn't see this Strat in the oob route guide so I am assuming this is a new discovery and may be worth looking into see if there is other places in the game where you can abuse checkpoints and loading gates to go out of bounds.
