What is the deduction for a cast to horizontal with incorrect body alignment on Level 4 bars?

When assessing a cast to horizontal on Level 4 bars, body alignment is a critical factor for judges. If a gymnast executes the cast but does not maintain the correct body alignment, it can impact the overall execution score. In this context, a deduction of up to 0.20 is appropriate for incorrect body alignment when the gymnast is at horizontal. This deduction reflects the importance of body position in demonstrating control and form during the skill. Maintaining proper alignment is crucial for not only the appearance of the skill but also for safety and performance standards.

The other potential options for deductions do not accurately reflect the established guidelines for judging this particular movement in gymnastics. The 0.10 and 0.05 deductions are generally reserved for minor errors or less significant faults, whereas the up to 0.30 deduction tends to be applied for more grievous mistakes or a combination of faults that substantially affect the execution of the skill. Therefore, the correct deduction aligns with the established scoring rubric for Level 4 bars.
