How do we fly? Doom eternal speed jump trick? Lets figure this out!!

How does this ramp jumping trick work? Could be good for speed runs and such to cover ground fast. Can not make it happen even 10% of the time as of posting this video.

To do Super Jump you go to a ledge, look down, open weapon wheel, And as you start to fall off spam jump loads of times. It works better if you use mouse wheel to do it. It's also tied to FPS so the higher the FPS, the higher the super jump. Stairs can also be used for Super jumping
