Alter 4.D.2 to allow for change of score caller

4.D.2. In non-officiated play, the server normally calls the score, but the server’s partner may call the score if the server is unable to call the score. The person calling the score shall not change during the game without notifying the other team of the change before the serve.
4.D.2.a. If the partner of the person designated to call the score for the game inadvertently calls the score, no fault shall be called and the person designated to call the score shall recall the score to start the rally.

4.D.2. In non-officiated play, the server normally calls the score, but the server’s partner may call the score if the server is unable to call the score. The person calling the score shall not change during the game.

There are instances where one partner has a very soft voice and it is difficult for the receiving team to hear them. This change would allow that team to have the partner call the score during the game to help keep the game moving along without the receiving team not fully hearing the score being called.
