[1] Sports which incorporate a degree of difficulty in scoring include bouldering, cross-country skiing, diving, equestrianism, figure skating, freestyle skiing, gymnastics, rhythmic gymnastics, surfing, synchronized swimming and trampoline.
Degree of difficulty is typically intended to be an objective measure, in sports whose scoring may also rely on subjective judgments of performance.
The International Swimming Federation computes the degree of difficulty of dives according to a five-part formula, incorporating height, number of somersaults and twists, positioning, approach, and entry.
[3] In figure skating, each jump element is assigned a base value, reflective of its difficulty.
A greater number of flips and twists increases degree of difficulty scores for jumps.
