Overuse
Since the inception of figure skating's cumulative points-based judging system, many skaters have used the Biellman position in various elements, such as spiral sequences due to its added point value regardless of the quality of the position. Moreover, performing a Biellmann spin after 8 revolutions in a layback spin adds a "difficult variation," which can increase the point value of the spin.
The Biellmann spin also has the distinction of being classified as a difficult variation of both a layback and an upright position spin, meaning that a person could include the Biellmann in either spin and it would still be counted as a one-position solo spin.
Due to its increased use since the inception of the new judging system, the 51st International Skating Union Congress passed a resolution that places a limit on the number of times that a Biellmann position may be used in a skating program.
