How much is deducted for a brush or touch of the landing surface with hands?

For level 10 gymnastics, a deduction of 0.3 is applied when there is a brush or touch of the landing surface with the hands upon completing a dismount or landing a skill. This deduction reflects the severity of the error, as using hands to stabilize a landing can indicate a loss of balance and control that is significant enough to warrant such a penalty. This deduction serves not only as a standard penalty but also emphasizes the importance of clean and controlled landings in gymnastics, which are crucial for demonstrating skill proficiency. The specific value of 0.3 particularly aligns with the established criteria used in the Code of Points when evaluating the overall execution of a routine.
