I've been told to say as little as possible to the players (by officials and camp instructors much higher up than myself).
1 and 1: "1 and 1"
2 shots: "2" (regardless of shooting foul or double bonus)
Back end of a 1 and 1 or second shot: 1 only
PS this may be a midwest thing.
IMO the players should know the situation and when they can/cannot move on a throw. This is called being well coached (maybe an oxy)
and having their head in the game
