What's the impact on scoring for a gymnast who has bent arms during execution?

When a gymnast displays bent arms during the execution of their routine, it negatively impacts the overall execution score. This is due to the standard of form and technique that judges are looking for; straight arms are often a requirement for demonstrating strength, control, and precision in the movements. A deduction of 0.3 reflects a significant violation of these expectations, as it indicates a marked lack of proper form that detracts from the overall aesthetics and execution quality of the performance. This level of deduction serves to emphasize the importance of clean lines and technical execution in gymnastics, aligning with scoring guidelines that prioritize skill proficiency and presentation.

The other potential deductions would not accurately reflect the impact of such a significant error in form, making 0.3 the appropriate choice in this context.
