left/right is objectively optimal here because you get the dash refresh sooner and dont have the speed reset
left/analog right at the top, can hold it from the cdash, and let go of analog right before dashing, then swap to right/analog left for the gate wall, continue to hold this as you dash through since its a right dash and you dont have to worry about greed as much, careful not to dash early or you'll dash off the wall
saves 0.14 on a perfectly greeded cyclone to the bottom, and 0.02-0.1 on a good cling -> downpress, however it saves more than that generally since this is bufferable consistency where the other strats have a lot of timing going on, probably closer to 0.3 for most people
