For a feature classified as Level 3 in synchro skating, how many different feature groups must be represented?

For a feature classified as Level 3 in synchro skating, it is required that three different feature groups be represented. This level emphasizes the complexity and variety of skills demonstrated by the team. Each feature group typically includes various elements such as blocks, intersections, and transitions, which showcase the skaters' abilities and enhance the performance's overall artistic impression. By encompassing three different feature groups, the team demonstrates a higher level of technical skill and creativity, fulfilling the criteria established for Level 3 features. This requirement differentiates Level 3 from lower-level classifications, which demand fewer feature groups, thereby better illustrating the progression in synchro skating difficulty and artistry.
