Regardless of Yuzuru wears on his face or otherwise, it doesn't change that if he keeps progressing this season and skates his FS to its fullest potential (2 quads and 7 triples and all the transitions in between) and keeps skating the SP the way he did for 3 of his 4 competitions this year , he has the potential to have a TES of nearly 100 points that will make him a key contender at Worlds even if other skaters get higher PCS.
Indeed. His TES potential is just incredible. Despite being a non-international event, I think what happened at the Japanese Championships is a good example of what could happen at Worlds. Hanyu lost to Takahashi in both segments in terms of PCS (Takahashi even getting an insane 96 for PCS in the free), but still won overall as a result of his amazing TES. The other guys will have to do very well technically this year.
