What is a key factor for referees to improve accuracy and performance on the court?

The correct choice highlights the importance of proper distance and maintaining a tight open angle for referees to enhance their accuracy and performance during a game. This positioning is crucial because it allows referees to have a clear and unobstructed view of the play, ensuring they can accurately assess situations and make informed calls. By being at an appropriate distance, referees can observe player movements, interactions, and potential fouls with greater clarity.

A tight open angle further aids referees in seeing the action without obstruction. This positioning allows for better judgment and a more comprehensive understanding of the play dynamics, which is essential for making correct decisions in real time. Overall, the effectiveness of a referee in making calls relies heavily on their ability to observe plays clearly and precisely, which is achieved through optimal positioning.
