How much deduction is applied for insufficient amplitude in a salto dismount?

In gymnastics, the concept of amplitude refers to the height and overall execution quality of a skill, including dismounts. When a gymnast performs a salto dismount, it is crucial that the salto is executed with sufficient height and distance to demonstrate control and technique. If the salto is performed with insufficient amplitude, it does not align with the expected standards for a Level 9 routine.

A deduction of 0.30 may be applied in cases where the amplitude falls below the acceptable level. This deduction reflects the importance judges place on both the aesthetic presentation and the technical execution of the dismount. Insufficient amplitude can lead to a lack of momentum which impairs the landing.

It's important to understand that the other options correspond to different levels of deductions for various errors. For example, 0.20 and 0.10 deductions might apply for minor mistakes or slightly lower amplitude, but they do not address the specific case of a significant amplitude deficiency. The absence of deductions as an option suggests that judges recognize insufficient amplitude as an error warranting a clear penalty. Therefore, the correct deduction for a noticeable lack of amplitude in a salto dismount is indeed 0.30.
