This men's event just shows what a great loss it is to have Patrick and Javi retire (and Yuzuru injured). Rather than the win in this WC is invalid, the scores the top men 'earned' here should be marked with an (*). Without the three above PCS became such a joke. If Patrick was there, I wouldn't think some judges are shameless enough to score Chen's SS in the 9s. I like Shoma, and I am rooting for him to pull through his injury (or better yet, rest!!) but compared with the Yuzuru's 48 PCS Chopin, Shoma's showing tonight shouldn't get anywhere near 46 PCS. Same with the other top men, except for maybe Boyang who have shown quite an improvement in his skating.
How does Kolyada have more PCS than Nathan?..
Huh? What did he say?
In general, a program is much harder to execute if you put quads in there (assuming you don't strip out all the choreo/transitions in between, which I don't think is an issue with Chen's).
Transitions: in/out of quads are harder compared to transitions in and out of triples. Of course, this is up for debate, because sometimes dumbing down to a triple allows a skater to add more transitions to up the quantity. Difficulty is open to interpretation too as some transitions are harder to execute, and some transitions are harder because of having to execute them prior to more difficult elements. There's some ambiguity there.
Skating skills (balance/precision of foot placement) is harder and you need stronger technique to execute quads versus triples. It's harder to exhibit balance/control/glide on more difficult choreography, it's harder to do on more difficult jumps.
Performance: quads are also more exciting to see than triples which benefits the Performance/projection aspect (an audience is more involved if you're attempting and executing riskier elements).
Choreography/Composition: a quad, being harder, provides a greater musical highlight compared to a triple, thus creating a more exciting/interesting mood. It is also much harder to execute the rest of a program's choreography well when you have greater difficulty of jumps as it tires you out more.
Interpretation: when a quad is landed on a musical highlight it is more impactful, which can lend itself to more impactful expression. A program is simply more impressive with difficult elements, and brings out the character more compared to a skater doing easy jumps that people have been doing for 20 years.
Of course, that's not to say that a program without quads can't get 10's (or close).... but that should be reserved only for skaters who still show excellent level of overall skating and strong programs - like Ge, Rippon or Brown, IMO.
