Dash Dancing: How to move the stick fast enough

[Predatoria]

I've seen some players do a move where they pretty much spin in place, kind of like in this video:

I went ahead and looked at this, at least with Ridley, and found by methodically going frame by frame in training mode, to do this, I'd need to move the analog stick left to right to left six times in the timespan of one second in order to reach the minimum threshold to perform a dash dance, as you must reverse the dash on the 5th frame of the dash animation (or less) to meet the requirement. (Basically, going left right left right left right left right left right left right, within one second of time, on the analog stick).

My question is.... how? How do players physically move their analog stick that fast? Is there some trick to it that I'm missing? It seems almost superhuman to be able to move the analog stick as fast as it seems like you'd need to in order to do this.

In particular, again for reference, you can see Kvothe do the same move here (and several other times) during this tournament, in particular at time 1:18 (right after the singular fireball during Captain Falcon's respawn).

I've tried, and the best I can do is do this on 1/2 speed in training mode.

I'm bred from the days of Melee dash dancing where mistakes would result in tap jump screwing you, so it comes pretty naturally to me by this point in Ultimate. There's a definite rhythm to it and it can vary from character to character.. some have much worse options than other ones. As a Falcon main I'm pretty used to dash dancing all the time and it's pretty much reflex. Don't practice it on 1/2, just keep at it and at it and at it at full speed until you get it. Ridley may not have a great one though, I'm unsure.

Inkling has a lightning fast, amazing dash dance.. one of if not the best in the entire game for sure. It's not the best comparison for a character like, say, Ridley.
