What must be done with slashes in the points column before switching sides during a deciding set?

In a deciding set of volleyball, it is essential to keep an accurate score and ensure that all relevant information is clearly visible. Transferring slashes in the points column to the far right column serves several purposes.

First, it enhances clarity for players, referees, and scorekeepers, allowing everyone to have a clear understanding of the game's point progression. This is critical in a deciding set, where the stakes are highest, and every point counts.

Additionally, placing the slashes in the far right column helps maintain an organized score sheet. This organization helps avoid confusion regarding the current score and any changes that might occur during the match, such as timeouts or substitutions.

Other choices do not meet the requirement for clarity and accuracy necessary in a match situation. For instance, leaving slashes unchanged or marking them lightly could lead to ambiguity in the scoring, while stating they only apply to the first set disregards the ongoing relevance of the score as the deciding set progresses.
