Kim made a major mistake in the short and wasn't perfect in the long either. Her performances also lacked the usual spark probably due to the injury. The results were so close because no one was perfect at the competition. Nakano had the cleanest performances to the naked eye but she had a lot of URs, which are heavily penalized under this system. To me, Mao and Nakano gave the most inspiring performances at that Worlds. Despite the big fall in the LP, Mao got up and delivered the rest of the program quite well. The results were close but I felt it was the right winner in the end. Can't say the same about the other medalists. This was the competition that I felt Kostner was the most generously scored.
