hi lambda, pleasure to meet you too, and mousiope :D
my confusion does seem to be with the wording/terms
jump+crouch is not the order you should do things in to be efficient.
crouch+jump 'crouchjump' = normal jump
I do think you should call it demoman ctap, or just ctap as it has the same tapping and release of crouch which I assume is to mash the hitbox into the ground, so fundamentally its the same technique.
and on that note do you have distances compared to a regular sticky jump?
the one in the video can be done with a regular jump np
