In the change of type of spin feature, what must at least 1/2 of the team do?

In the context of synchro skating and the change of type of spin feature, for a valid execution, it is required that a minimum of half of the skaters in the team either transition from a solo spin to a pair spin or vice versa. This showcases the versatility and coordination within the team and emphasizes the dynamic nature of the performance.

When interpreting the skills demonstrated in the spins, successfully executing this requirement highlights the team's ability to creatively exhibit both types of spins, contributing to the overall composition and technical complexity of the routine. It allows for variation in the routine that engages the audience and judges alike.

Exploring the other options, focusing solely on solo or only pair spins would restrict the performance's creativity and fail to meet the requirements of showcasing a change in spin type. Performing different spins simultaneously does not necessarily fulfill the condition of changing spin types within the same formation, making it inadequate for this specific feature. Thus, requiring at least half of the team to engage in the change from solo to pair spins or vice versa embodies the essential element of adaptability and teamwork central to synchro skating.
