What is the point deduction for extra arm swings during the landing phase?

During the landing phase, extra arm swings are considered a minor deduction in gymnastics judging. Specifically, a deduction of 0.10 is applied for each instance of excess movement that does not aid in the control of the landing. This deduction acknowledges that while some movement is natural and may occur, excessive or unnecessary arm swings indicate a lack of stability and precision in the gymnast's landing. Therefore, when judging a performance, this deduction reflects the importance of control and form upon landing, which is a critical aspect of a successful routine. This level of deduction aligns with the established criteria for assessing landings, reinforcing the need for gymnasts to display clean and controlled finishes to their skills.
