Moving during transitions is vital for good runs so here is all movement patterns for most levels. This does NOT include how long you should hold for.

W = Forwards, A = Left, S = Backwards, D = Right, 2 letters are a combinations of 2 directions

Sub 1 : You start the timer when you move so there is no point

Sub 2 : A, W, D, W,

Sub 3 : A, AS, S, D

Sub 4 : A, S, D, W

Sub 5 : A, W, D, W

Sub 6 : W

Sub 7 : A

Sub 8 : A, W, D, W

Sub 9 : A, W, D, S

Sub 10 : W

Sub 11 : A

Sub 12 : D, S

Sub 13 : Too risky to make any movements

Sub 14 : S, A, WA, A

Sub 15 : D

Sub 16 : Risky but near the end of the transition I do : W, D

Sub 17 : S, A, S, D, W, A

Sub 18 : Risky-ish but : A, W, D

Sub 19 : too risky to do anything

Sub 20 : W

I Hope this helps this speeds up the learning progress for memorizing moving during transitions. I also recommend NOT moving your mouse unless you absolutely know what you are doing
