Start/Stop Clock Signals

[zebraman]

A raised fist is also a "stop clock" signal so we actually do signal the timer to stop the clock on all fouls. Perhaps the reason it isn't required on jump balls is because we are raising both hands already which is easy for the timer to see. ??

Anyway, you can't go wrong using NFHS mechanics in a high school game and using NCAA mechanics in a college game.

I like the raised hand prior to the violation for the same reason as JB said. It gives you a couple extra microseconds to process information and it prevents you from giving a signal too quick in case you have a double whistle with a partner.
