If there is a discrepancy between the official scorer's score and the visible device, which score is considered official?

The official scorebook is the authoritative record of the match's score in volleyball. In the event of a discrepancy between the official scorer's score and the visible device, the official scorebook takes precedence. This is because the scorebook is maintained by the designated official scorer, who is responsible for accurately recording all points, player substitutions, timeouts, and any other relevant information throughout the match.

The integrity and accuracy of the official scorebook are vital to ensure the match is documented correctly and can be referenced if disputes arise. The visible scoring device may have technical issues or errors that could lead to incorrect information being displayed. Thus, reliance on the official scorebook helps ensure that any adjustments are based on the most reliable and officially verified record of the match.

The option regarding the agreement between both teams may appear reasonable, but without official documentation, it could lead to misunderstandings or conflicts. Similarly, trends on social media are not reliable sources of information and can be based on opinions or provide inaccurate updates.
