Chan's PCS is inconsequential to him defeating all other skaters. For the sake of argument, your claim is true, judges should have lowered his PCS a little more due to a fall which knocked him out for about 4 seconds, what other errors do you feel should have also lowered his PCS given that you said errors?
He was behind the music at times. He even admitted that he made the mistake on the 2A because he was rushing to catch up with the music. At least his PE (9.00) and his IN (9.21) should have been lower, especially compared to Takahashi. Actually, last year his PE and IN were not much higher for a visibly better performance. I'm not arguing his win here, as you seem to think I'm doing. I just wish he had been scored more accurately to what he actually did.
