It always bugged me that I couldn't use some of the glitches/tricks that I had discovered when making the S rank run. The 'stand on pot' trick in particular, because it really seemed like it could be used somewhere.
And, lo and behold, it can.
Time saver using stand on pot glitch

I just made this today while experimenting. It saves 8 in-game frames; since I wasn't heavily focusing on precision, I'm confident even more can be saved. With the proper optimization, maybe even 30 frames? More?
The glitch when i first found it enabled me to grab the pot beneath me, which gave me 1 frame of 'standing on ground' status, which let me jump or slide and carry the pot with me, but not jump slide. When I did this, I found I could do a normal slide jump without grabbing, and I was close enough to the top to not need to carry the pot with me.
"That's a slide jump, >C boost, ^C boost, drop-pot cancel, ^C boost, land on pot, slide jump off pot, >C boost, boost grab to the ledge maneuver." (sorry, I couldn't resist.)
It saves some frames for the S rank run, but I'm not certain about the gold gem run. When I tried to grab the pot below me, the pot was falling too fast, and I did a funny "land on pot-fall-land on pot-fall-land on pot" thing. Bringing the pot up and over the ledge is important for skipping the 4 grenades that you need to shake into a bomb. Maybe it's possible to grab it, and throw it over, then use a 1 frame of standing on ground to follow it?
Anyways. Since emulation is still not perfect, I'm still not doing a run. But, just making sure this discovery is out there.
