Her 3Lz looks good enough to me. There is always room for improvement in skating, but I think with her already challenging layout I do not want her to be hung up on it at the risk of the rest of a program.
I know the JO is not as important a competition as Grand Prix events, but I still think the PCS gaps between her and the rest were just wrong. Considering Ms. Asada's effortless gliding, near-clean execution, her beautiful lines and musicality, I think she should have gotten a Chan-like advantage over the rest of the skaters in this competition. There was not a single moment she slowed down and struggled to maintain speed while performing an intricate program. I would give a point advantage to her ice coverage alone - it is such a stark contrast to many youngsters (who are not really youngsters any more) whose skating is limited around the center of the rink like squirrels running on wheels.
Unlike some others, I like this program more than the Rach 2, choreography-wise. This program really highlights Ms. Asada's strengths from the beginning to the end. There was not a segment that felt "forced" or "muscled out," and it was a treat to watch her executing difficult elements with a seeming ease. That aspect of her skating must have been so dramatically transpired to the audience and viewers alike in this competition, especially when you watch her skating before/after other skater(s) whose every move appears laborious and tortured. I also like that she looks relaxed before/during/after the program. I know the Rach 2 will remain some fans' sentimental favorite among Ms. Asada's programs, I think Madame Butterfly has a potential to become even greater.
