I agree a little bit with what you said but don't bash how Mirai did at 4CC when she was very ill and after she flew from Japan to the US and then to Taipei in a week. I'm sure if this was not her only opportunity to skate at an international championship this season she would have skipped it.
Why do we always hear this same excuse when she skates so poorly. Just like last year at Nationals. If she is so ill, the smart thing would be to withdraw.
