Thank you! I didn't know how GOEs were awarded before. Now that I've learned of it;
1) Applies to neither (Ms. Kim or Ms. Asada)
2) Applies to both
3) Applies to neither (?) --> Honestly I have no idea what this one means
4) Advantage Ms. Kim
5) Applies to neither or both
6) Advantage Ms. Kim
7) Advantage Ms. Kim
8) Applies to both
It makes sense now why Ms. Kim racks up more GOEs (especially +2 on 3Lz/3T) from her jumps.
1) applies to both... unexpected entry could be like doing an Ina Bauer or spread eagle before the jump, even if there is a moment of preparation to get into the proper entry position for the jump... so say Yu-Na's Ina Bauer into her 2A+3T would be a variation on entry
2) is obvious, some jumps must be entered a certain way, 3-turn, etc.
3)varied position in the air could apply to Mao (raising one arm on the 2T on her 3A+2T), the raising of the one arm is a variation on the traditional position of the arms during the jump... a male skater made it very popular to have the one arm up... it makes the jump more difficult, because it is harder to generate the spin with the torso. Another example would be delaying the rotation (ie. not rotating the jump immediately upon take off), although this really is only normally seen on the axel... there even is a variation called the "delayed axel" (although not recognized by the CoP) where the skater does not rotate until the very end of the jump right before landing.
4)both have good height and ice coverage (Mao's 3A has excellet height and ice coverage) and Yu-Na' 3Lz+3T is fantastic.
5)Mao has a better extension exiting her jumps... but both have creative exits on some (an example: Sasha would often lift her leg into a split after some jumps)
The rest is pretty self-explanatory
I saw someone mentioning spiral sequences and extensions and Yu-Na Kim's body type frail-ish or willowy body-type hindering that. I'm naturally flexible, but I've skated with others who or not... there is no reason that you can't have great extension with enough training, but skaters are earning +GOE's without it, so why bother? It takes A LOT of strength to hold your leg up (no catch-foot) and definitely wears you out. Try putting a 5lb wrap around weight on your ankle, lifting your leg back and see how fantastic it feels. Even if you are flexible, it takes a LOT of time to build up the strength (paticularly in the lower back, abs, hamstrings, gluts) to lift the leg higher. Just because you can do a split or are flexible doesn't mean that you can do it free standing (like in a spiral sequence). In Yu-Na's case, her flow, speed and ice coverage on her spiral grant her enough +GOEs so there really is no point in putting in tons of extra strength straining to be able to get the added extension... not to mention that by putting that added extension in, all she will be doing is tiring her muscles out even more, so it will wind up taking away from the quality of other elements (ie. jumps). In the end, the extra time to get it and the chance that it tires her out to the point where she won't get as high or as many +GOEs on other elements isn't worth it... but is it impossible for her to have that extension if she wanted it? No.
