In a collapsing feature, how many pi rotations are permitted?

In synchro skating, the concept of pi rotations refers to half-rotations typically performed by skaters in a formation or during a transition. When discussing collapsing features within a routine, the rules dictate the number of permitted pi rotations to maintain proper execution and flow.

In this case, the correct answer highlights that only one pi rotation is permitted during a collapsing feature. This limitation is set to prevent over-rotation and ensure skaters maintain synchronization and safety throughout the maneuver. The focus on a single pi rotation helps to preserve the integrity of the formation while allowing skaters to execute the transition smoothly and within the framework of the established rules.

The other options suggest a greater number of pi rotations, which would introduce complexity and could lead to potential safety risks, imbalance in the formation, and a lack of synchronization among the skaters. Therefore, the restrictions on the number of pi rotations are crucial for the artistry and technical precision required in synchro skating performance.
