Hey guys I'd like to know how these fast jumps and mid air kicks work.

I saw these strats in several Top Runs.

I know that the fastest jump is to First go right then attack and then jump. But in the top runs they do a mid air kick, is it caused by pressing attack in fly or different? If you know how please answer :)

I think it's just luck but try press them both around the same time e.g press " a then a frame later press jump than press a more"
