What is the requirement for utilizing two series of Different Types of Difficult Turns/Steps in a Step Sequence?

The requirement for utilizing two series of different types of difficult turns or steps in a step sequence is that each series must be executed on different feet. This allows for a more dynamic and varied representation of the skater's technical ability, showcasing their skill in handling turns and steps across both feet. Incorporating different feet demonstrates versatility and balance, as the skater must control and perform the maneuvers effectively on each foot.

Executing each series on the same foot would limit the complexity and variety of the performance, as it would essentially reduce the scope of the skater's movements and skills being highlighted. The focus is on creating a well-rounded step sequence that captivates the judges with a display of technical proficiency across various movements, which can't be achieved if only one foot is used for both series.

While other options touch on different aspects of skating technique, they do not align with the specific requirement regarding the use of feet in the execution of the difficult turns and steps in a sequence. The emphasis is primarily on the need to showcase proficiency on both feet to meet the criteria effectively.
