I disagree. Czisny's planned content could put her in the top 5 at Worlds, in that second tier behind YuNa/Caro/Mao. I think it is extremely unlikely that she would skate clean given her form the last few years but I don't think the sport has surpassed her peak level by any means.
This. There are only 6 age-eligible skaters who can consistently get their 2A/3Ts or 3/3s ratified: Yuna, Gracie, Kaetlyn, Elizaveta, Carolina, and Akiko. Akiko, Carolina, and Yuna can match Alissa on presentation, footwork, spirals, and can come close to her in spins. Those skaters have a clear advantage over Alissa if they and Alissa skate clean programs. The others--Gracie, Kaetlyn, and Elizaveta--all have deficiencies in spins, spirals, and overall presentation (they still look immature on the ice in spite of their impressive technical content) that somewhat nullifies their technical advantage. In 2010-2011 Akiko, Carolina, and Yuna competed along with Miki Ando (who had similar technical prowess), Rachael Flatt (who could also get her 2A/3T or 3/3 ratified at the time), Mao, etc. If Alissa was good enough to place fifth at Worlds that year--and let's be honest, if the judges hadn't lowballed her in the short program and on her component scores in the long, she would have deservedly snagged the bronze medal--she can do just fine in the 2013 environment as long as she skates clean programs.
