So what is the best instruction to give to the table crew about when to switch the arrow? If you tell them, "Don't switch the arrow until the ball is touched by a player on the floor", those instructions incorrectly cover this case. Is, "Don't switch the arrow until the ball is touched by a player on the floor or unless the thrower throws it away", too complicated? Is there something better?
