This was done on the current newest version of the game Version 1.3.3 along with a mod that let me show the hitboxes so you it can hopefully help show exactly what's going on in this stage.
The biggest difference over this patch and some old patches is you can't do the frame perfect clip through the ground and under the acorn machine, that was patched out but we have found a couple other very fast ways of doing it.
An advanced version of the "Two-tone hop" which involves getting over the machine and is demonstrated wonderfully by SBDWolf here https://youtu.be/oVlQJe4pnfA?t=25 (He has gotten a 34.04 as his best time with it but that clip demonstrates the strategy).
And then there's the Ninja clip which is what I use in this video. It involves damage boosting, getting really far into the machine, facing away from the machine and then pressing jump and EX at the exact same time. If performed correctly it will clip you through the machine. Doing the clip at a really high speed is very difficult at least for me but I wanted to demonstrate how fast the stage can be with this strategy.
