It is well understood. It was just ignored in Sochi. (why? your guess is as good as mine ) My personal gripes against these younger skaters were that they do not finish their moves! They go onto the next element in a hurry without letting me enjoy whatever it is that they supposedly have just done. These uncleanness occurring in succession throughout a whole program, the whole thing looked like a mess.What the judges of late have been ignoring is the quality of the moves. (I´m not talking artistry.) We saw with Gracie Gold where she landed the jump but there was a wobble in it. Or Yulia. Her foot is in the right direction but her body is askew. Adenia did the tricks but the line and flow out weren´t there . The mature, top skaters develop control. They land with everything in position, no settling. They have devloped all the little muscles that plant you firnly in position on landing.
It makes a difference. I don´t know why in figure skating this is not understood. In diving, for example, many high-school athletes can do triple layouts, etc. But only the Greg Louganis-es rotate with everything perfecdtly aligned and enter the water soundlessly. A 15 year old just isn´t develooped enough to understand much less perfect all these details.
