For a performance that shows insufficient variety of shapes, what deduction can be applied?

In gymnastics, the deduction for insufficient variety of shapes during a performance is crucial in evaluating the execution and presentation of routines. A deduction of 0.1 is applied when a gymnast does not display a sufficient range of body positions and shapes throughout their routine. This standard is set to encourage gymnasts to include a diverse array of movements that showcase their flexibility, strength, and creativity.

The performance should ideally include different shapes such as twists, arches, pikes, and straddles. A lack of variety can make a routine appear monotonous and can detract from the overall performance, making this specific deduction important for maintaining high standards in gymnastics presentations.

The other options, while related to deductions, represent different levels of severity for varying errors, which are not applicable for the specific case of insufficient variety of shapes that justifies a smaller deduction.
