Kiira is one year older than Mao... and I don't agree she's losing ground to Kiira or Mirai, where would those two have been that impressive? Obviously Mao lost ground to Ashley for example, but that's too because Ashley has really stepped it up. Mirai could beat Mao (without Mao making too many mistakes, I mean), but she really would need to get herself together, which I didn't see at Finlandia.
And I never said Mao needs the 3A to be competitive. Of course it gives her a huge advantage, but she wouldn't need it looking at the current ladies field. If clean, she could have 7 triples (though the lutz with an egde call), gets high PCS, has easily Lv4 spins with +GOE and step sequences now Lv4 with +GOE. That's hardly something I could see Kiira or Nagasu doing recently... the 3A isn't her biggest advantage. Her biggest advantage is her pure beautiful skating, when she gets it together.
That might change till Sochi though, with the young Russians and Yuna coming back.
