Binge's point still stands, if a player has used a certain control method for such a time and worked up to a level of play, they won't switch for a 1mm benefit for a 1 in a million chance. There's a pro running around using a 360 controller or something.
But, I would think these are totally implausible considering the force at which players hit the buttons, you will always bottom out and have at least 4mm of travel before you could even again actuate a press, though most probably 6mm. Does that cushion pad cause the switch to bottom out at the actuation point?
Anyway, I thought most standard links have a 12 frame window, and your lowest chance links, parries or blocks are 4 to 6 frames?
A 1 frame window would be considered impossible.
