What penalty is given for insufficient sureness of performance throughout a routine?

The penalty for insufficient sureness of performance throughout a routine is indeed a deduction of 0.2. This deduction applies when a gymnast demonstrates a lack of confidence in their skills, resulting in unsteady movements, hesitations, or a lack of fluidity throughout the routine.

Judges assess not only the execution of a routine but also the overall presentation, which includes the gymnast's attitude and presence. A noticeable lack of certainty can detract from a routine's overall aesthetic and perceived difficulty, prompting this specific deduction.

This deduction is an important component of scoring because it emphasizes the need for gymnasts to perform with not just technical skill, but also with confidence and poise, which are essential qualities in gymnastics at advanced levels.
