In general feature requirements, what proportion of the team must execute the same feature(s)?

The correct response reflects the standards set for synchro skating, which require that at least half of the team executes the same feature(s) in order to meet the criteria for that part of the performance. This requirement ensures that a significant section of the team is synchronized and engaged in the execution of the elements, enhancing the overall unity and cohesion of the performance.

Having at least 50% of the team executing the same features demonstrates a clear level of synchronization, which is essential for the scoring and evaluation of the routine. It allows the judges to perceive that the features are a true representation of the team's skill and ability to perform in unison.

In this context, the other proportions, such as requiring all skaters or only a third of the team, would not adequately demonstrate the level of cohesiveness that judges look for. A requirement of at least two-thirds might be overly stringent for certain features, complicating the performance without necessarily adding value to the execution. Therefore, having at least half of the skaters perform the same feature strikes a suitable balance for scoring in synchro skating.
