which may be considered difficult variations, are counted towards the team's total number of revolutions. Only positions, whether basic or non-basic, must be performed by the partners at the same time. If a skater falls while entering into the spin, they can perform another spin or spinning movement immediately after the fall, to fill the time lost from the fall, but it is not counted as a solo spin combination. A change of foot, in the form of a jump or step over, is allowed, and the change of position and change of foot can be performed separately or at the same time. Pair teams require "significant strength, skill and control" to perform a change from a basic position to a different basic position without performing a nonbasic position first. They also have to execute a continuous movement throughout the change, without jumps to execute it, and they must hold the basic position for two revolutions both before and after the change. They lose points if they take a long time to reach the necessary basic position. Pair teams earn more points for performing difficult entrances into their spins. Difficult flying entrances count, although backward entry into the spin and a flying camel do not. All entrances must have a "significant impact" on the spin's execution, balance, and control, and the intended spin position must be achieved within the team's first two revolutions. The rules surrounding difficult variations, which also apply to single skaters and to both partners, are also worth more points. There are 11 categories of difficult solo spin variations. Spin combinations Both junior and senior pair teams must perform one pair spin combination, which may begin with a fly spin, during their free skating programs. Pair spin combinations must have at least eight revolutions, which must be counted from "the entry of the spin until its exit". If spins are done with less than two revolutions, pairs receive zero points; if they have less than three revolutions, they are considered a skating movement, not a spin. Pair teams cannot, except for a short step when changing directions, stop while performing a rotation. Spins must have at least two different basic positions, with two revolutions in each position performed by both partners anywhere within the spin; full value for pair spin combinations are awarded only when both partners perform all three basic positions.
