She's not a naturally flexible skater, and I suspect she lost a lot of her flexibility during her break. She commented that getting her spin positions back was one of the most difficult things about this comeback. (She did not say the same about her jumps...)Just watched the youtube vid of Yu-Na's SP and it is nice to see that even after the break, her jumps still look strong and crisp. She had a minor error on her 2A but overall, she did a good job.
Couldnt help but notice her lack of flexibility in her spins (compared to her previous spins in the past).
IMO, I think her PCS are way too high but again this is just my opinion...
