Sasha's GOT is literally using a theme from a popular series people liked and most of the program is setting up jumps, some cool transition but there's never an attempt to sell the routine, i wouldn't give it above 7 for performance, and maybe even 6 for interpretation.
And in contrast with what people say, about Trusova not being artistic, i actually think the way she moves is good, you can work on it, she could be much more artistic with a better packaging and some work on posture and gliding, but nobody bothers, it's all about the quads, the levels, and the speed.
The way you describe and "unpackage" PCS is how, at least for me, it should be judged.
Interpretation and performance have little to do with skating skills and transition: the 1st two being purely artistic the latter being technical, and compsition should really be related to how the program is build and put on the ice.
Yet we rarely see more than 0.5 votes between the best and the worst of the 5 categories, like the judges are just adjusting aroung a base "artistic score" they give to the skater.
Like the could not be a girl with marvelous blades, but no musicality or ability to convey the program idea to the audience, or a girl with little technique but that build with her trainer and choreographer a great program composition.
Another thing I hate is that PCS goes up with TES.
You can bet money that Sasha without quads will be badly punished in PCS while will get great numbers if she lands 3 of them.
That could be ok with performance and transitions (impossible to skate a transition while recovering from a fall) because the program will be flowing, but what could possibly have to do with skating skills, intepretation and especially composition?
I appreciate Sasha's interpretation in the short when she's skating and not just preparing for jumps.
That's the problem with quad filled programs (even for men) so much time is spent preparing and recovering from jumps that the actual skating is reduced to a minimun, and that should (theoretically) impact composition, interpretation and performance.
