How long to stop?

[danreeves1973]

Called a 13-14 boys game tonight, OBR used. I'm BU. Visiting coach politely asked (no, really) me about the home pitcher not coming to a complete stop once he came set. He tried to say they have to come to a stop for a full second. Conversation was polite, I told him I'd keep an eye on both teams for that.

My question: after looking at OBR, it says "...The pitcher, following his stretch, must (a) hold the ball in both hands in front of his body and (b) come to a complete stop."

In my situation, kid was pausing, was short pause, but IMO he did come to a complete stop everytime, there was a discernable time of no movement. Just not long enough for the coaches taste.

What are the best practises for watching for this, as in how long a stop is long enough?
