For insufficient extension/opening of a tuck/pike before landing dismount, how much is the deduction?

The correct deduction for insufficient extension or opening of a tuck or pike before landing a dismount is 0.2. In gymnastics, it is crucial for gymnasts to demonstrate proper body position and extension during their routines, especially during dismounts. Insufficient extension can affect the overall aesthetics and technical execution of the routine, hence the deduction reflects the judges' assessment of form and positioning.

A deduction of 0.2 signifies a noticeable but not excessive error, indicating that while the gymnast's performance was commendable, there was still a minor flaw in the execution that did not meet the standard of excellence expected at Level 10. Judges are trained to evaluate movements and body positions critically; therefore, when gymnasts do not fully extend or open their bodies during the dismount, it impacts the overall score, warranting this specific deduction.

The other options reflect greater penalties, which would apply in cases of more severe mistakes or errors such as a complete lack of form. Understanding this nuance helps in accurately assessing performances and knowing how judges differentiate between slight and major infractions.
