The only time I've ever used the arm pumping is in Ceres Station, because I can actually see how much time I'm saving on the clock. I only did it for fun. My question is, does it need to be done at a specific speed (I always tried to tap the button once every time Samus' foot hit the ground), or should it be pressed as rapidly as possible? And should it be alternated (R-L-R-L) or just one at a time (L-L-L-L, or R-R-R-R)? I've only seen the 32 once, haven't had time to really scrutinize it yet. It looked like he was alternating, but with some variations, like L-R-L-L-R-L-R-R (paradiddles, anyone?) or something like that. Hitting the button when Samus' foot touches the ground would probably be about 5-6 times per second. If pressing it as fast as possible is the way to go, I could probably get 10-12 per second (alternating), though I'm not sure how long I could maintain it (I'm a drummer - I have very fast fingers).
