Officials should be professional in the use of the signals and should not attempt to draw attention to themselves by use of unapproved, emphatic or theatrical signals.

That being said, when a try is capped by the defender so it doesn't leave the throwers hand & he lands with the ball.
I often see officials at all levels use the clap-clap (vertically) prior to their held ball signal. Thoughts?
