What is the maximum deduction for a vault performed with legs bent?

The maximum deduction for a vault performed with legs bent is indeed 0.30. This deduction reflects a significant fault because bent legs during the vault can indicate a lack of control and proper technique, impacting the overall impression of the gymnast's execution. In gymnastics scoring, deductions for form faults, such as leg positioning, are crucial, as they directly influence the gymnast's final score. Deductions are designed to be proportional to the severity of the error, and a bent leg is a clear visual cue that the gymnast has not maintained the required body alignment and position during the vault execution. Therefore, the deduction of 0.30 for this specific error is consistent with the scoring guidelines, which seek to reward proper technique and form in performances.
