Egg Totem Theoretical 5.50 with Amy
Dumb. No human is ever doing this. But good to know it's technically possible
Must make some space, and run for ~0.30 seconds to make space from the left wall
Buffer down, and instastop by doing a jump then the next frame, hammer twirl
Instantly spindash into tap jump for 1 frame. I later realized after this that sometimes doing medium-height jumps makes it easier to reach the spot she needs to jump on for some reason, so that might be better / more lenient.
Full jump at around the 3rd ring
As Amy lands the first hit, do the hammer twirl attack on one of the few perfect frames she "flings" right - this is sometimes outright impossible, this is sometimes 1 frame, and this is sometimes two or three 1-frame perfect windows. BASICALLY, IT'S RANDOM!
At this point, Knuckles can just spindash easily to victory without even turning around. But Amy's spindash animation doesn't reach, so she can't do that.
Tap left to turn left, and hammer ASAP. Just hammer hammer hammer.
Amy's first hammer input must be between 2.15-2.18 to have a chance at the perfect 5.50 time.
If she hammers earlier than 2.15, then it'll overlap too much with the first hit's iframes and won't count
Every hammer input must be made exactly 31 frames apart. Starting the first input at 2.15 gives 2 frames of leeway, 2.17 gives 1 frame, and 2.18 gives none.
With a save state here, and human mashing, I typically get like a high 5.6x or low 5.7x, so maybe I'll be satisfied enough with that. The asshole who hid all of his videos has a 5.87.
