The definition of Release Move has been updated this year and now applies to Stunts and Pyramids alike. The updated definition is:
When the top person becomes free of contact with all people on the performing surface; see “Free Release Move”
This definition means skills including a pyramid leap frog and a braced flip are release moves. Even with the top person remaining in contact with a bracer the skill is a release move if the top person is not in contact with anyone on the performing surface.
Note – The information in this article is based on the August 27, 2015 release of the rules.
