It had nothing to do with the the upping of tech content, and everything to do with the system rewarding sloppiness if you're doing quads. It would rather you fully rotate and fall then double jumps. Everything in this system depends on judges who score anonymously, and tech callers who don't seem to call things fairly and seem to have too much power.
It also has to do with the skaters who are out there. Chan is notorious for under-performing and getting held up. Hanyu has stamina issues. Fernandez has been up and down all year. Takahashi is in the sunset of his career. Jason was green and it showed, he was way nervous out there, and was slow. There was no one who has EVER taken hold of a whole season. Chan fell his way to three world championships. Hanyu has nearly ALWAYS fallen on that 4S in competition, and was only doing it to fully rotate and get the points.
We may rip on Plushenko, but he KNOWS how to skate under pressure.
