Which combination receives the maximum CV bonus of 0.4?

The combination that receives the maximum CV bonus of 0.4 is accurately identified as the one involving a series of skills that maximizes difficulty and connection value. In this case, the combination of a C leap followed by another C leap and concludes with a D jump is particularly noteworthy.

The scoring for connections in gymnastics often rewards combinations featuring elements that not only demonstrate the gymnast's technical proficiency but also display complexity in their execution. The requirement for a combination to earn the maximum bonus often includes varying the skill levels, adding different types of elements (like leaps and jumps), and ensuring that they are performed in a sequence that highlights cohesion and flow.

In this case, by including two C leaps which are of higher value than lower-rated elements, and concluding with a D jump, the gymnast successfully meets the criteria that allows for the maximum connection value. Each component contributes to the complexity and technical merit of the routine, leading to a higher CV bonus.

This choice effectively illustrates how well-executed combinations of varying difficulty can enhance a gymnast's score, particularly in categories where connection value is a determinant of overall performance.
