How is the general element requirement for pyramid structures defined?

The general element requirement for pyramid structures specifies that the back line of the pyramid must be longer than the front line. This requirement is crucial for maintaining the proper formation and stability of the pyramid, especially since the back line supports more weight and provides necessary balance for the skaters positioned in the front. Having the back line longer than the front line contributes to the overall aesthetic and the technical execution of the formation, ensuring that the pyramid appears cohesive and well-aligned. This guideline helps in effective synchronization among skaters and allows for a more dynamic and visually impressive display during performances.
