How much is deducted for extra arm swings during landing?

When evaluating gymnastic performances, particularly during landings, judges assess various factors that impact the overall execution of a routine. Extra arm swings during a landing indicate a lack of control and stability, which is fundamental to a strong finish. The deduction for such movements is set at a range of up to 0.1 points. This allows for a standardized method of penalizing those minor errors in execution while acknowledging that their severity can vary depending on additional context throughout the landing. The specificity of "up to 0.1" captures the idea that slight adjustments or movements can vary in impact, and not all extra swings might warrant the full deduction, thus more accurately reflecting the gymnast's performance quality.
