This overemphasis on start/order and cleanliness over actual skating quality applies for all disciplines...here are just a few examples...
For Ladies: I would say one of the worst examples was Polina Edmunds in 2014. An unheralded junior skater (who fell in her free skate) was given HIGHER PCS than recent Grand Prix Final medalist Ashley Wagner; Ashley was averaging a whopping 15 points higher PCS in the free skate alone internationally (65 vs 50). Polina's inexplicable placement was really what robbed Mirai of her Olympic chance in 2014, and also gave Ashley bad press. Ashley doesn't have the best skating skills, but when compared to Polina in all aspects in PCS she was in a completely different league. Polina in 2016, Karen Chen in 2017 were other examples--just because Polina and Karen skated cleanly does not mean they should get 10 points more than their international GP PCS scores (Ashley's dropped from her gp scores in both instances); the flow and skating skills still aren't there, even if you skate clean.
First of all, Polina Edmunds wasn't exactly 'an unknown junior skater'. She had made it to the JGPF that season, one of the very few US skaters to get there.
Let's look at the Nationals:
SP-TES:
1. 40.34 Gracie-3z+3t, 3lo, 2a
2. 37.14 Polina-3z+3t, 3f, 2a
3. 36.97 Mirai-3t+3t, 3lo, 2a
4: 32.51 Ashley-3f+2t (-GOE), 3lo, 2a
SP-PCS:
1. 32.20 Ashley
2. 31.78 Gracie
3. 29.61 Polina
4. 28.57 Mirai
Scores:
1. 72.12 Gracie
2. 66.75 Polina
3. 65.44 Mirai
4. 64.71 Ashley
The short program is a technical program, and it was not unreasonable for Polina to place 2nd as she, with Gracie, had the highest TES. The SP scores from 2nd to 4th were very close.
FREESKATE TES
1. 71.37 Gracie 3z+3t, 2a+3t, 3lo, 3fe, 3z, 3s+2t+2t, 2a
2. 66.21 Polina 3z+3t, 3f+1lo+3s, 2a, 3fe↓, 3z, 3lo+2t, fall
3. 65.62 Mirai 3f<+2t, 2a+3t, 3z, 2lo+2t+2lo, 3f, 3lo, 2a, time violation
5.
58.48 Ashley 3f+3t<↓, 2a, 3s, 3lo^2a, 3ze, 3lo<↓, 3f+2t, 2 falls
FREESKATE PCS
1. 68.30 Gracie
2. 61.67 Polina
3. 61.55 Ashley
4. 60.68 Mirai
There was a 0.12 difference between Polina's PCS and Ashley's. But Ashley had a very messy FS and in fact was placed behind Samantha Cesario in the FS.
OVERALL SCORE:
1. 211.69 Gracie
2. 193.63 Polina
3. 190.74 Mirai
4. 182.72 Ashley
Looking at the scores, it makes one wonder why Ashley was chosen for Sochi instead of Mirai. But Ashley had made the US podium and the GPF multiple times in the preceding seasons, and was a GPF medalwinner, while Mirai struggled in both previous Nationals and the GP. THAT was why Ashley went to Sochi and not Mirai. Polina's placement had nothing to do with it---she just skated very well and earned her silver medal.
As for Ashley's higher international PCS scores, Ashley skated much better in her GP events than she did at Nationals 2014. If she had skated the way she did at Nationals in the GP, her TES
and PCS would have been considerably lower, and she wouldn't have made the Final.
