How much is deducted for a backward or forward swing under horizontal on the uneven bars?

A deduction of 0.1 is applied for a backward or forward swing that is under horizontal on the uneven bars. This specific deduction reflects the importance of maintaining a strong body position and the requirement for the gymnast to achieve horizontal or above during their swing movements. When a swing falls below horizontal, it indicates a lack of control and height, which affects the overall execution and presentation of the routine. Therefore, the deduction is designed to penalize the failure to meet these critical performance standards, ensuring that gymnasts are rewarded for maintaining proper technique on the apparatus while striving for execution excellence.
