I don't want to get into a word definition battle for sure, but people discern things differently. If there is a change in direction of the hands, and that change if direction occurs in the same spot each time, it can be predicted and ceases to be deceptive. I have then discerned there was a stop. If minimum duration of time mattered greatly, there would be a time mentioned in the rules.

Obviously the pitcher can't begin their leg lift or slide step until their hands are either stopped, or moving in the same direction as their lift or slide step. Otherwise you have a balk.
