I think Mao would have to improve a lot to have a chance at gold. Two years before Vancouver she was still doing 3/3s, and then she lost them and tried unsuccessfully to improve her lutz. Her current level is off her 2010 level, and far off her 2008 level. If I were her, I'd just settle for taking the edge call on the lutz and work on getting a 3/3 back because she could build up quite a lead in the SP with a 3A and a 3/3.
