The tragedy is not that Carolina receives strong PCS for absolutely gorgeous skating. The tragedy is that Mao did not receive the same for her Madame Butterfly in 2016. More ladies should work for what those two bring to the ice, IMO.
This.
Which basically means that it is not like "True artistry is rewarded with high PCs", but "some selected skaters get top PCs whatever they do".
While I´m more sport person, I could live with the "PCs reward artistry" thing. But its not really, because Mao was not getting 75 PCs for a program with 4 triples. Mao was not getting random +2/+3 on all her elements just because she is Mao.
