What is the deduction if there is a noticeable arch in the body position during the tap swing forward on Level 4 bars?

When evaluating the deduction for a noticeable arch in the body position during the tap swing forward on Level 4 bars, a deduction of 0.20 is appropriate. This is aligned with the guidelines laid out for Level 4 gymnastics, which emphasizes the importance of maintaining a strong, straight body position throughout the skill. A noticeable arch indicates a lack of control and proper form, which affects the overall execution and aesthetics of the routine.

A deduction of 0.20 reflects that the gymnast displayed significant deviation from the ideal position but does not warrant a more severe penalty, as it does not indicate a complete failure of the skill. This measure encourages gymnasts to strive for better body alignment while still acknowledging that there was effort and execution of the skill.

In contrast, larger deductions, such as 0.30 or 0.40, would typically relate to more severe errors or omissions in performing the skill, like major form breaks or failure to complete the skill entirely. Therefore, 0.20 is the correct deduction that accurately represents a noticeable arch without escalating to the higher thresholds reserved for more critical errors.
