How is the service round recorded when a player continues to serve after the switch?

In volleyball, when a player continues serving after a switch, the procedure for recording the service round maintains clarity and accuracy in tracking who has served during that rotation. In this case, the correct procedure is to not make any check mark in the service round number. This indicates that the current server has not changed and continues to serve without interruption from the usual rotation.

The absence of a check mark serves to document that the server remains the same, which is essential for keeping accurate records of service turns and ensuring that all players are accounted for in their respective positions during the game. This method helps officials and scorekeepers maintain a clear understanding of the server's order and prevents any potential confusion about which player is serving at any given time.

In contrast, adding a check mark or filling in the box for the next server would imply that a new player has begun their serve, which is not accurate in this scenario. Similarly, creating a new entry in the points column would also misrepresent the status of the server. Thus, by not placing any check mark for the service round number when a player continues to serve after the switch, the official scorekeeping accurately reflects the ongoing situation on the court.
