Do not underestimate the max distance possible with hh momentum, or momentum in general.

We are able to go farther than 5 blocks with hh momentum, especially with multiple blocks. I posted the 5b with practical momentum (two blocks of headhitter momentum) instead of four+ which, if done correctly, would make it tremendously easier.

Barring that, the jumps you use as reference are not the "longest" jumps possible. This will not lead you to the actual "max" distance one can jump.

Additional information:

Jumping around a neo - It is possible to minimize the distance lost for neos which lowers the "max" value for listed for how long a quad neo is. I am working on finding out what exactly causes this and what is needed to consistently replicate it.

Speed - Speed actually changes some of the mechanics that you'd have without speed.

I. The way you move in air: Although this is minor, it does make a difference for jumps like this (If you'd like, i can go further in depth on this. Just send me a private message).

II. The optimized method of doing a triple neo. The majority of players simply run and jump, there are methods that make the jump itself easier.

a. Strafing with the wall: There is an "ideal" position to be in while doing a triple neo. This is one of the mechanics that minimize the distance lost for neos

b. The timing of when to turn inward for landing on how it is done: Depending on how the neo is done for the "air" section of the jump, it is sometimes better to turn later, rather than earlier.

Speed has more changes, each having its own "perk." I will not be listing any more as it will be in my book, haha.

With all that being said: Quad neos are possible. In terms of length, i believe it is the hardest jump possible, requiring everything to go in your favor.
