Double Y turn/spin
Double split turn
Chellsie Memmel (USA)
Or, as the code of points calls her, Chelsia Memmel. Score another one for the CoP.
The double Y turn is a surprisingly new skill on the scene, and it’s a bit remarkable to me that it was still available to be named after someone even when Chellsie Memmel was competing.
Still, attempts to squeeze out every possible tenth of difficulty value through complicated turns is a rather recent phenomenon, a necessary reaction to the tumblies’ ability to throw out multiple G+ tumbling skills. As such, the double Y turn (or more accurately, the 1.35 Y turn + weird stumble-lean) is an increasingly standard part of floor composition.
