What deduction is incurred for a round off if the gymnast fails to pass through vertical?

When evaluating a round-off in gymnastics, a significant aspect is the gymnast's ability to pass through a vertical position. Failing to achieve vertical during this skill indicates a lack of proper technique and may affect the overall execution. The specific deduction for not passing through vertical in a round-off is 0.30. This deduction reflects the importance of vertical alignment in ensuring the gymnast completes the skill with precision and control.

Passing through vertical is pivotal for both safety and the aesthetic quality of the performance; thus, the higher deduction captures the severity of this error in execution. Other options reflect smaller deductions that are more typical for less critical errors, but the failure to achieve vertical has a more substantial impact on both execution and the overall score.
