For a vault landing, what is the maximum deduction for a slight hop or small adjustments of feet upon landing?

The maximum deduction for a slight hop or small adjustments of feet upon landing in gymnastics vaulting is indeed 0.1. This reflects the precision required in judging landings. During a vault, a slight hop represents a minor error in control, and such an adjustment typically warrants a deduction that is not severe. A small adjustment indicates that the gymnast maintained relative control but was unable to achieve a completely stable landing, warranting the specific deduction for these small errors.

In gymnastics scoring, deductions reflect the gymnast's performance quality based on specific criteria, and a slight hop or minor maneuver indicates a less-than-perfect landing without necessarily compromising the overall skill execution or vast control. Thus, a 0.1 deduction is suitable for reflecting this level of error in the landing phase after a vault.
