I don't have time to translate this now, but here's a great interview with Mao's coaches (Nobuo and Kumiko Sato) from May 2012 on their hesitation to take on such a big deal skater, Mao's slow yet definite process of technical reform, her new attitude towards skating (showing interest in other disciplines like Ice Dancing etc), her maturity during the tough times and so on.
So they were saying all along, "This is a 3-year process. Please be patient for just a bit longer. We will get there"!
I've gotta admit when I saw Mao in Nice, I didn't expect this big a come back. What a skater she is!! Just like I didn't expect Yu Na to come back with the jump content she showed earlier in Germany and Korea. The Worlds will be sooooooo exciting! The ladies figure skating is BACK!
