In a vault, what is the deduction for total absence of extension during tuck or pike vaults?

In a vault, the total absence of extension during tuck or pike positions is a significant deduction because it reflects a lack of form and control that is expected at the Level 10 standard. When a gymnast is executing a vault in these positions, they are required to show a defined extension at the shoulders, hips, and knees.

A deduction of 0.3 is appropriate in this context because it indicates that the gymnast has failed to meet a fundamental technical criterion that is crucial for a properly executed vault. Such a substantial deduction acknowledges the critical role that extension plays in maintaining the integrity of the vault and ensuring safety, as well as the overall aesthetic of the performance. This level of deduction serves to reinforce the importance of form and execution in gymnastics, motivating athletes to strive for improvement and mastery of their skills.
