I like it because the no-jump second bump has a lot of things going for it:

1. It requires one fewer input (no A press for the jump)
2. It's super consistent (for me at least, once you get the hang of it), I think because there's simpler inputs
3. It gives you a nice quick bump that sets the elevator up pretty high for the 3rd bump
4. When I used the position hack, it always gave me a 9 or 10 bump. I never got an 8 or 7 out of like 50 times. Now, obviously that's not proof, but even if it's a super high frequency that's good. It allows for a pretty deep pipe entry using 3 bump method, as you can see in the video with one or two of the pipe entries.

I've tested, and it loses a FR.

How many times have you tried it?

@lul_ecks_dee. Several. I lost 2 fr after hitting WJ one-time, when you normally only loose one hitting WJ.

It doesn't lose the frame rule for me

Maybe it's just slower enough so that if you hit WJ you lose 2 framerules, but fast enough to make it normally.

It's easier for me but you can barely get the framerule. I only get it when i'm entering the first 3 pixels of the pipe, but it's not to difficult to do ^^ Thanks for that trick :D that's going to make runs easier for me ^^

I think I am going to remain with normal, BC I don't want to lose 2 FR from WJ.

well getting wj pixel is hard LOL

Not really

i only got wj once in a run ^^

why are we talking about wall jump? There's no wall jump in 4-2

when jumping down to the warpzone in 4-2, mario occasionally hits a walljump pixel on the rightmost wall, which often slows him down enough to lose an extra framerule

I use this no jump 2nd bump when I go for fast 4-2, it's really useful for me
