What is the maximum deduction for failure to keep legs joined in a Level 4 stretch jump with a 1/2 turn?

The maximum deduction for failure to keep legs joined in a Level 4 stretch jump with a 1/2 turn is indeed 0.60. This deduction falls under the category of form issues, specifically addressing the position of the legs during the execution of the jump. When performing a stretch jump, it is crucial for the gymnast to maintain a tight body position, with the legs straight and joined together.

If the legs are not fully together, judges will assess the degree of separation to determine the appropriate deduction. Since this particular element is designed to show control and stability, a significant deduction like 0.60 reflects the importance of this technique in the overall assessment of the gymnast's performance. Maintaining leg position not only affects the aesthetic quality of the jump but also indicates the gymnast's overall body control and execution skills, which are critical at this level.

While lower deductions might apply for minor form breaks, the specific nature of a stretch jump emphasizes the necessity for precision, hence the higher maximum deduction for this particular error.
