If a rider performs skills with an obvious lack of control, the Mastery score goes down. Judges are looking for body form that demonstrates good control and 'mastery' of the unicycle. Holding a skill for a longer amount of time also indicates a higher level of mastery for that skill. This is beauty of body form and movements. This involves positioning and movements of the body during the act.
Judges look for deliberate movements over uncoordinated movements made to retain balance.
Free leg stretched with toes pointed, head up and chest lifted, arms out and relaxed, smooth transition from one body position to another. This is good body form. Leaning forward, head down, sudden waving of arms, hands and fingers splayed are examples of poor body form. Judges are looking for the rider's ability to capture the audience with his or her confidence on stage, eye contact, facial expressions, and making the audience a part of the act. This is also the category in which a rider can take advantage of a missed skill by the way he or she covers up the miss.
