For me, the issue is not even weird PCs scores given, but lack of consistency in scoring.
For example, where the 10 points gap between Jin and Chen comes from?
Do you think Evgenia Medvedeva’s PCS should be 11-13 points higher than other girls her age, e.g. Zijun Li?
Chen’s PCS rise is in fact the same as Medvedeva’s PCS rise. Medevdeva was the top junior before she turned senior. She won everything in junior and got bronze at Russian senior national in 2014-2015 season. (She won two JGP and got bronze in both JGPF and JWC in 2013-2014 season.) She continued to deliver after she turned senior. She didn’t become Russian no.1 until she won GPF in 2015 and her PCS kept rising.
Chen was the top junior before he turned senior. He won everything in junior, got bronze at US senior national before he had a surgery and withdrew from JWC & WC in 2015-2016 season. (He won two JGP and got bronze in both JGPF and JWC in 2013-2014 season. He skipped quite a few competitions due to injuries in 2014-2015 season.) He continued to deliver after he turned senior. He didn’t become US no.1 until she medaled at GPF last year and his PCS kept rising.
USFSA is doing exactly the same thing Russian Fed is doing. Why do Russian Fed and USFS push Medevdeva and Chen when they have so many skaters to choose from? Because both Medevdeva and Chen are the most consistent skaters (with no major weakness) in their respective country and they have been consistent since they were junior (or even novice).
Russian girls struggle with puberty. Most of their senior girls are one-season wonder. Medevdeva is the only Russian girl in recent years that stays at the top for more than one seasons.
American men struggle with quads. For years, American champs have been quadless and don’t have the tech to compete at international level. Chen is their first man with consistent quads in recent years to compete at the top (and he lands more quads than everyone).
You often hear fans saying Medevdeva will go into a slump soon due to puberty. You also hear many fans says Chen will break himself soon due to doing so many quads.
You see a few threads opened whenever Medvedeva wins a competition. Now, a few threads are also opened when Chen won something this season.
I know fans have issue with the way PCS is judged. But PCS (and GOE too) is really tier based. When you are in 1st tier, you get 1st tier goe and pcs, i.e. 2-3 goe & high 8s - low 9s pcs. When you are in 2nd tier, you get 2nd tier goe and pcs, i.e. 1-2 goe & high 7s - low 8s pcs. When you are in 3rd tier or in junior, you get 3rd tier goe and pcs, i.e. 0-1 goe & high 6s – low 7s pcs.
When you compare the pcs of a 1st tier skater with a 2nd tier skater, you will always see a big gap not justified by their performances & skills. It’s always been this way. When you compare the pcs of skaters in the same tier, the difference between their PCS is not huge. If you compare the pcs of Hanyu (94), Fernandez (93), Chan (92), Uno (92) and Chen (88), the difference isn’t that big. This allows the top tier skater with the hardest tech and cleanest performance to win and avoids controversy. (The deduction for a fall is only 3 points for a triple and 5 points for a quad. A pcs gap of over 5 points means a skater with a fall can outscore another skater with a clean performance. So you can’t really give significantly more than 5 points gap in pcs between two medal contenders if you don’t want to give controversial placements, especially when men and pairs attempt hard tech and fall so often.) When you give skaters of the same tier significantly different pcs and goe, you will see controversial results like 2012 WC and 2013 WC. In fact, after 2013 WC, we haven’t seen many controversial results at major championships. Top tier skaters don’t have significant goe and pcs advantage over each other. They only have significant goe and pcs advantage over 2nd tier or 3rd tier skaters.
How do you become a top tier skater? You need to have something really outstanding that no one has and you need to consistently deliver.
P.S. I’m a bit surprised that Medvedeva’s fans are also among the ones that complain about Chen’s PCS when Chen’s PCS rise is exactly the same as Medvedeva’s PCS rise.
