Thanks for the replies! That makes a lot of sense, I'll look into both dual jump and the auto jump glitch.

Hey people, I'm a relatively new runner of super meat boy (my best time is a 25:08, though in the leaderboard as of the time of this post it's a 29:47 or so), and I've been watching some of the higher level runners and I keep seeing this technique where they jump between 2 narrow walls incredibly fast. For example, the world record run on Forest 1-4 and, to a greater extent, Hospital 2-17. Is it just as simple as "press button faster" or is there some technique to it? Thanks in advance for any advice!
