re Wakaba - you can never know for sure what age someone will go through puberty. Do any of the Japanese (or otherwise Wakaba) fans know how much her body has changed the last couple of years? I just ask because she's now 14 and while she is short, her stature looks like someone who is currently growing (her current build looks like someone currently going through puberty). Maybe someone who has seen her more within the last couple of years can comment.
In any event - Wakaba's jump technique is very well formed/sophisticated - even the flip, which has given her trouble, has good height and a clean landing.
Skaters who see their jumps fall of going through puberty are often those who did not have good technique to begin with (although, obviously, this is not always the case). No guarantees- but Wakaba strikes me as someone whose jumps will hold up.
Re Wakaba's PCS - yes, there is a gap between her TCS (the highest in the long program by 4 points) - but her PCS was still 3rd highest overall - and she is one of the youngest skaters in the field - and doing her first year at jr. Let's not exaggerate 'complaints' over Wakaba's PCS - they are very superior. I suspect her performance ability will pick up with experience - and she does have a natural 'musicality' (to go alone with her high end skating skills).
IMO, Wakaba's first year on the junior scene can only be described as a 'resounding success'!
I have already seen a great deal of progress on the spins...although she needs much more work here. But from what I understand, the Japanese way is to get the jumps first, early on, and then work the spins, arm flapping etc. It wa certainly the best program I've seen her skate-good for her!
