What is the value of a floor stretch jump with a half turn?

The value of a floor stretch jump with a half turn is indeed 0.40. This skill is generally evaluated based on its execution and the difficulty involved. A stretch jump involves a jump with the body fully extended and arms in a specific position, and incorporating a half turn adds to the complexity of the skill.

In gymnastics scoring, different skills are assigned specific values reflecting their difficulty level and the execution required. The half turn in the jump not only increases the level of technical difficulty but also requires more control and precision, which is why it is rewarded a higher value compared to a standard stretch jump.

Thus, the score of 0.40 is established within the context of the gymnastics code of points, where skills are systematically categorized and awarded specific values based on their execution and difficulty.
