Вот детали для юниоров
"Junior: There must be a minimum of eight (8) revolutions in the landing position which must be the same as the flying position. No previous rotation on the ice before the take-off is permitted.
When the flying sit spin is required in the short program, only the prescribed "Flying" position or its variation is permitted, this position must be attained in the air, and changing foot on landing is permitted.
For both Senior and Junior, the required eight (8) revolutions can be executed in any variation of the landing position."
Вот вам на всякий случай протоколы КП с юниорского ГП, посмотрите - ни у кого нет прыжка в либелу со сменой ноги. Если бы было можно, все бы делали, чего зря баллы терять?
