There are also changes in how twists are judged. Before, one of the requirements for the more difficult level was three base positions on each leg; now, three positions on one leg suffice. Previous requirements were unreasonably harsh and unreasonable, though many athletes complied with it. This change has allowed my team to decrease the time and number of rotations on side-by-side spins in both programs. Now, they spin for three or four seconds less, which reduces errors. That element is relatively undemanding physically, but it requires a very high concentration. A combination spin with a change of leg requires about 15 rotations, and most of the small errors at competitions happen on the spins.
