What type of skill must the E skill be to qualify for an extra 0.1 bonus on beam or floor?

The requirement for an E skill to qualify for an extra 0.1 bonus on beam or floor is that it must be an acrobatic skill. In the context of gymnastics, acrobatic skills refer to movements that involve significant skill, strength, and control, typically characterized by their dynamic nature, such as flips, twists, and landings. These skills are essential for demonstrating the gymnast's technical ability and creativity.

While artistic, tumbling, and balance skills are also important components of gymnastics routines, they do not specifically meet the criteria for earning the extra bonus tied to the E skill classification. Tumbling skills, for example, may fall under acrobatic skills but are more focused on the series of flips and rotations. Balance skills pertain to maintaining stability on the beam or during certain elements, while artistic skills generally refer to the overall presentation and style of the routine. Thus, only acrobatic skills will satisfy the conditions necessary for the additional bonus point.
