Literally just realized this about pinpoint

I’ve been using pinpoint since 21 and never knew that the little circle at the bottom of the circle will shrink and when it gets to the smallest size is when how you time it up but I’ve always just went off my pitchers delivery and kinda timed it up with when he releases the ball lmao. But on a side note does anyone else have a problem on Xbox elite controller where pinpoint just doesn’t work sometimes?
