Which of the following is NOT true of scoring reining?

In reining competitions, scoring is an important aspect that reflects the quality of the horse's performance and the rider's skill. A score of 80 is indeed considered an average performance; it signifies that the run met all the required elements with a basic level of execution and presentation. Scores are typically awarded based on how well the horse executes maneuvers such as spins, stops, and lead changes, with attention to precision, speed, and style.

A score of 70 serves as a baseline for gauging performance, where judges can assess if a run is sub-par or if it meets the minimal expectations for a competitive effort. Scores above 70 indicate progressively better performances, while those below indicate areas where the horse or rider did not meet criteria.

Moreover, scores can go higher than 70 and can be adjusted positively for exceptional performances, reflecting the growing complexity and finesse in a reining run. However, the misconception in this question arises with the option suggesting that 5 is the highest score possible; in fact, reining scores range typically from 0 to 80 and can exceed 80 in competitive scenarios. Therefore, the assertion that 5 is the highest possible score is not true.
