How to do DC switch early for glitchless

im pretty consistent at this now. main parts are:

getting in a ok position (around just to the right of the ledge)

do ess right and target the wall, if you target too late then you will mess up the camera when you go to twist. You can still make it just have to change control stick angles to fit camera (for example if you twist right after you target you can just hold down the whole way)  (you can do this without targeting the wall too but being on the wall seems most consistent).

when the beam gets close hold down from 1 frame. next frame hold shield. next frame backflip. after backflip release shield and hold left (I know that sounds weird but it keeps you from going backwards)
