What must all skaters do during the synchronized spin element unless stated otherwise?

In a synchronized spin element, all skaters are required to use the same feature unless stated otherwise. This means that they should execute the spin in a uniform manner, coordinating their movements to create a cohesive visual effect. The use of the same feature ensures that the team appears synchronized, which is a hallmark of synchro skating. It highlights the precision and teamwork essential to this discipline, showcasing the unity and harmony of the group.

In contrast, using different movements would detract from the synchronicity expected in this element. Changing positions every revolution or performing separately would also interrupt the formation and flow that is critical in establishing a successful synchronized spin. Therefore, uniformity in the feature chosen for the spin allows the team to demonstrate their skills collectively, fulfilling the element's requirements.
