Trick jumps, yay or nay?

[Mousikos]

These are all double jumps. If you make two jump within 250 ms (I think that's the number), you end up going faster/higher than normal. In edge jumping, you use the crouching on the edge of an object, say a box, to end your jump and you jump again. In hax jumping, you press shift+crouch twice in the same time period to do it. The other, harder way to do it is to jump crouch jump crouch jump crouch (pre jump) that let's you accomplish this (I forgot why and it's generally less accurate than the first method, which is still less accurate than, say, a bind). The double jump is the same concept, except you bump your head against something (say a low ceiling), that ends your jump and forces you back down. just hit jump again and it'll be as if you edge jumped
