What are the deductions for a beam salto twisting dismount if 45-89 degrees are missing?

When evaluating a beam salto twisting dismount, the deductions for missing twists are based on specific angles. In this case, if the gymnast is missing a twist within the range of 45 to 89 degrees, a deduction of 0.15 is applied. This deduction reflects the significant loss of difficulty and control that stems from an incomplete twist, as it directly affects the overall execution and presentation of the dismount.

The rationale behind a 0.15 deduction is that it indicates a notable deviation from the expected performance. The judges are trained to observe such details, and a twist that is less than full impacts both the technical score and the overall quality of the routine. Therefore, awarding a 0.15 deduction accurately penalizes the gymnast for not achieving the level of difficulty associated with a complete twist in that dismount.
