The correct answer to the L3 Pyramid Inversion quiz is the skill is Illegal in Level 3 as performed. Included in the Level 3 Pyramid rule allowing a top person to pass through an inverted position while connected to a base and a bracer is:
The top person must remain in contact with both the bracer and the base throughout the transition.
The transition ends when the top person comes to a stop, which in the video is the bottom of the dip during the catch. The bracer does not maintain contact with the top person until the bottom of the dip of the catch, therefore the skill is not allowed in Level 3. This is a different standard than what’s required for Level 4 & 5, which requires the bracer(s) to remain in contact with the top person until the top is in contact someone on the ground, not the bottom of the catch.
The explanation is based on the 2017-18 version of the cheer rules dated August 30, 2017.
