What flaw in the execution of a cast results in a deduction of up to 0.30?

Insufficient amplitude in a cast refers to how high or far the gymnast lifts their body away from the horizontal plane of the bar during the execution of the skill. In gymnastics, amplitude is crucial for showcasing the skill effectively. A cast should ideally reach a position that elevates the gymnast’s hips well above the level of the bar. When the amplitude is insufficient, it indicates a lack of proper technique and strength, which detracts from the overall execution of the skill. This is significant in the judging process and results in a deduction of up to 0.30, as it does not meet the expected standard of performance required for a well-executed cast. This deduction also reflects the level of difficulty and the expectations of accuracy in movements at levels 4 and 5.

Other possible flaws such as incorrect timing, insufficient push, and faulty body position may also incur deductions, but they do not specifically result in the same maximum deduction for amplitude issues. Understanding the importance of amplitude helps gymnasts focus on achieving the right body positioning and motions to fulfill judging criteria effectively.
