What is the minimum execution requirement for the first feature in the moves element?

The correct approach for the minimum execution requirement for the first feature in the moves element is that it must start with a difficult feature. This requirement emphasizes the importance of showcasing a high level of skill and technical ability right from the beginning of the execution. Starting with a challenging feature sets the tone for the performance and demonstrates the team's capability and preparedness.

When the first feature is difficult, it reflects the overall quality of the program and allows the judges to assess the skaters' technical proficiency early on. This strategic placement of a challenging element can be crucial in scoring, highlighting the team's strengths and creativity in their choreography.

In contrast, beginning with a basic feature, as suggested in other choices, would not fulfill the requirement for minimum execution. While basic features can have their place within a routine, they do not carry the same weight in demonstrating the skill level expected at competitive synchro skating events. Similarly, there is no specific stipulation regarding the number of skaters in relation to this requirement, making the correct focus strictly on the difficulty of the first feature.
