When must features be executed during the performance of different feature measures?

The execution of features during a synchro skating performance involves a level of precision and synchronization that is crucial for achieving the desired technical evaluation. The correct option asserts that features must overlap with the start of the next feature. This requirement is centered around maintaining continuity and flow within the performance.

In synchro skating, timing and synchronization among skaters is imperative to create a cohesive visual performance. By having features overlap, skaters can smoothly transition from one technical element to another, which enhances the overall execution and presentation value of the routine. This overlap ensures that while one feature is being completed, the next is already in motion, reinforcing the synchronicity that defines the discipline.

The other choices suggest varying degrees of separation or a lack of coordination among features, which would detract from the overall performance quality expected in synchro skating. Maintaining overlap in feature execution supports the intricate patterns and formations that characterize competitive routines, demonstrating both the technical skill of the skaters and their ability to perform in unison.
