When the left side team is serving first, how should the first service rounds box be marked?

When marking the first service rounds box, it is crucial to indicate which team is serving and to maintain clarity on the scoring and rotation. In this scenario, when the left side team serves first, marking the box with an "X" only on the far right signifies that the left-side team has taken serve. This marking system allows both teams, officials, and spectators to easily track turns and team positions during play.

Using an "X" on the far right specifically illustrates that the serving team is positioned on the left side of the court. This marking convenes the understanding that the first serve has been executed from that position, effectively clarifying the game's progression. Other methods of marking the box, such as using "X" on the far left or both sides or a check mark, do not align with the standard protocol of indicating the serving team's position and may lead to confusion during the match.
