So I found this trick with the trampoline, but I am not sure if this is actually a trick or a glitch. What do you need to do to jump so high with only "one" bounce is you need to crouch during the jump, and as soon as you hit the trampoline the first time, uncrouch, and the trampoline will hit you a second time in a short period of time, and it will make you jump very high.

I am asking this because this route is gonna be faster than the route that is used for glitchless% right now.

that looks more like a glitch tbh but im not sure
