My friend accidentally heard of an ISU judge talking to an ice-mom, the talk was technically that, PCS (and even GOE) is subjective and it shows how high you place in the judges' views.
Sad but frankly, judges did not write Javi off even he messed quite the whole season, but they already wrote Yuzuru (and Patrick too) quite a bit at WC.
It was clearly looking at the GOE and PCS to see whom the judges believe to be their top (or who they or their bosses want to put on top).
Judges do not give scores based on true quality. This is the truth. They scores based on reputation and of whom they believe and want to be on top.
This time, at WC it was NOT Yuzuru whom they want. Simple as that. But he forced them otherwise. The more they do not want him, the more they HAVE to give it to him. And frankly he has had enough reputation now, they can score him quite low and score other higher, but they will not hold him down to the 2nd tier level. He is still considered 1st tier.
We shall see how they will react next season.
