Just spent roughly 30 minutes in AA trying out the different skins (that I have currently) and seeing what I could learn from just going back and forth in the first section and have the following. If you find similar or different results I would be grateful for your input. If preferred, I can provide my recording and time stamp it if I get the time to.

5 Minutes as Chair: 7 Hops 5 Minutes as Dev Ball: 11 Hops, 1 Edge Stop 5 Minutes as Toilet: 8 Hops, 1 Edge Stop 5 Minutes as Horse: 7 Hops, 1 Edge Stop 5 Minutes as Chair again: 8 Hops

The "Edge Stop" referenced is an odd occurrence I've only noticed in this test where I would move forward off the edge of one of the short platforms at the start and all of my movement would be abruptly stopped just after I am off the raised floor. The gap between the Dev Ball and the other skins is due to a stretch of movement where I did not adjust left or right and only held forward and boosted and was able to hop three times in a row. Though, since the Dev Ball model is a misshapen sphere, I can't tell what angle I was at to hop that consistently.

I did spend an extra 5 minutes with the skins above trying to intentionally position the chair's hitbox in certain ways to see if it's a specific angle, but I couldn't really figure out the angle. I did however get my chair stopped in a certain way that it would lay flat on it's side and rotate 90 degrees forward with a jump and no directional input. I kept rotating and swapping skins and believe that all of the skins use the same hit box.

I also tried cross referencing some speedrun recordings to see if the chair's movement was different at high speeds vs low speeds, but the only thing I could discern was that the chair seems to make abrupt corrections if it isn't tumbling enough. It seems that at higher speeds it makes these corrections less, though these corrections only seem to happen while grounded long enough so that might be why.

I'm not sure if there's already a community somewhere that discusses this kind of stuff or has figured this kind of stuff out, but I'll ask here just in case.

I've been practicing Appliance Avenue to get into speedrunning this game and keep noticing that my chair occasionally will clip something and get a small hop off the ground. Is this due to the model of the chair clipping into the ground? Has anyone noticed if other skins do this more or less? And if this problem is lessened by smoother skins, would different in game or workshop skins (mainly thinking about the Dev Ball) invalidate submitted runs?
