What is the total deduction if a gymnast does not complete a required 1/4 turn on the dismount and also fails to maintain vertical?

When evaluating the dismount of a gymnast, judges look for specific execution criteria, including the completion of required turns and the maintenance of a vertical position upon landing. In this scenario, if a gymnast does not complete the required 1/4 turn on the dismount, a deduction of up to 0.30 is applicable for that specific error. Additionally, if the gymnast fails to maintain a vertical position upon landing, there is another deduction of up to 0.20.

Combining these deductions gives a total of 0.30 for the incomplete turn and 0.20 for the vertical failure, leading to an aggregate deduction of 0.50. The explanation provided suggests a focus on the total possible deductions given each specific execution error, clarifying how these deductions are cumulative. The total deduction precisely captures the impact of multiple faults during a performance, which is consistent with the rigorous standards of gymnastics judging.
