The average (mean) PCs score in the 2019 Worlds FS was 80.86. The mean TES at Worlds was around 81.52 (only 2 skaters out of 24 scored more than 100 TES, which is the current PCS max). So if you take the average of all skaters, the average TES of the overall field pretty much matches the average PCS going by the FS at the most recent Worlds. If you modify the PCS scale, you need to think about how such changes will affect the *whole field*.
This is a very interesting stat, and you make a good point.
One thing that is lost in this discussion is that in any scoring system, we'd want the cream to rise to the top. That's what happened here.
I don't think the results would have been much different in a 6.0 system, at least at this competition.
We're acting as though this scenario hasn't played out before. Young guns use technical firepower to state their case against established skaters. They chase the top guy, and eventually catch him. Yuzu chased Patrick. Nathan chases Yuzu. Soon, another young gun will come after Nathan. It's the nature of all sport. The chaser is impatient, and the veteran does what he can to hold him off.
Those of us who have followed the sport for a while recall when Kristi Yamaguchi and Michelle Kwan were the "jumping beans" who were using better jumps to claw their way to the top.
