My old pal, Vinny Russo, head ref in NJ: “Unless the clock operator is slow starting or shuts it off a little early, four seconds is about as quick as it gets, " said New Jersey's chief ref and state tourney assignor Vinny Russo. "The mechanics for an official is one swipe, start the second swipe, then slap the mat. That’s still two seconds. For it to happen the two kids actually have to charge one another off the whistle and one his starts falling backward." I think Vinny probably said "one starts falling backwards".
