Ok. Is there a practice ROM for double jumps? I think that is where this is at now. I am pretty sure I have to either triple jump with quick retries (is that possible?) or hit either of two double jumps with long walks back and my success rate on double jumps right now feels like it is <0.7%. I really have no idea what I'm doing, I just hit "jump, wait till peak, scan, wait a miniscule amount, scan, wait a miniscule amount half as big as the last one, jump" and hope it works, and sometimes it does.
But it's too rare for me to do outside of a standing jump right now, and the only places accessible with a standing multi-jump that are inaccessible otherwise (to me right now) would need back-to-back double jumps (either 2 or like a million to climb up the waterfall chute in 2.8/3.8) and if I'm right about 0.7% then at 1 attempt per 4 seconds it will take around 16 straight hours for me to have a 50% chance of success and that sounds like practice ROM training time would be a better idea to me.
