What is the deduction for missing a turn of 90 degrees or more on the beam?

When a gymnast misses a turn of 90 degrees or more on the beam, there is a specific deduction related to the difficulty achieved during the routine. If a turn is not executed correctly and a significant error occurs, such as failing to complete the rotation, the gymnast may not receive the value assigned to that element.

Thus, opting for the lower value being awarded directly reflects the gymnast's failure to complete the turn as intended. This deduction is applied because the execution of the skill is vital to overall performance, and not achieving the required turn constitutes a significant error that impacts the quality of the routine.

This rationale explains why the choice regarding the lower value part being awarded is the correct answer for this question. It emphasizes the importance of technical execution in gymnastics, especially at higher levels such as Level 9.
