In areas you may think have glitches, I don't think they are. 4-2 is just using the jumping code to our advantage, not using wrong warps or anything like that. 8-4 is just jumping to a height that you can reach the pipe without turning around or slowing down.
1-1: I think this is the fastest it can happen.
1-2: I was unable to get the fastest 1-2; 1 framerule off.
4-1: I didn't take advantage of infinite jumps as much as I could have, but I was having some trouble with FPG.
4-2: Did the top clip on my own; not the fastest clip you can do with AEPLLG but still good.
8-1: Solid.
8-2 and 8-3: You can freeze the timer if you are high up enough This is used to avoid fireworks.
8-4: There's a wrong warp one can do in room 1, but I have no idea how that works. It saves time in WJ room, too. I just go the normal route.
I ended input on the first frame possible.

The only slow part (I believe) is Warm-up. I couldn't seem to hit him at the right time. Sparring is a frame faster (in-game) due to delaying the start of the fight.
