'Scuse me while I geek out on CoP/IJS stats.

Personally, I find the numbers fascinating and a heck of a lot more insightful than the meaningless placeholders under 6.0. (Though, I loved the beauty of a 6.0...)
At Worlds last year, she had one of her "bad days" and she got a 65 in the PCS portion for her FS. No one else in the ladies was coming close to that range during the Grand Prix this season. In fact, hitting 60 was already a feat. As a Olympic champ, she does have an advantage over others in terms of reputation. The same can be said for Virtue/Moir. This is not necessarily a bad thing since there are reasons for her having a higher reputation, which you obviously have listed in your argument.
Your original claim has two parts: 1) Yu-Na has a
reputation that puts her into
medal contention even on
her worst days and 2) this is "more so than other skaters." So she got 65 at last year's Worlds for one of her own weaker skates and this year's ladies haven't...but I don't see how this supports your argument. The question is did PCS--which is the mark that is more subjective than TES, and more susceptible to influence by reputation--place her into medal contention when she otherwise would not have been? And if so, has this happened more frequently than other skaters? The answer is a resounding no to both questions.
At 2010 Worlds, Yu-Na won the silver with a margin of 12 points over 3rd, and was very far off from 1st by a margin of 7 points. You could take away
12 points from her PCS, leaving her with the PCS total that Ksenia Makarova (8th in the LP) or Rachael Flatt (9th in the LP) got, and Yu-Na still would have won the silver. Why wouldn't taking away such a large chunk of PCS make a difference in the medal result? First, because this competition stunk, and a large number of top skaters had "bad days." :sheesh: Second, because even in one of Yu-Na's "bad days" (which is relatively speaking, of course), she accomplished difficult jumps and combinations that no other skater at that competition (or this season, actually) did: 3Lz/3T, spread eagle into a 2A/3T, Ina Bauer into a 2A/2T/2Lo, which helped her base value, garnered GOE and contributed to a high technical score, high enough to completely justify her ending placement on the podium, with or without any help from the judges in components. Yu-Na's overall placement (2nd) is identical to her TES-only placement (2nd).
Even if it hadn't been the same, Yu-Na, like other top skaters, arguably does deserve high components even if a performance has a few mistakes, but I don't have to make that argument because Yu-Na has earned her results technically without needing the generosity of the judges (i.e. reputation points) to boost her overall. I doubt you will be able to find a single past competition where Yu-Na earned a higher placement on the podium than what her overall TES total indicated, even on any of her bad days, which she hasn't had a lot of. Not Worlds 2010, Skate America 2009, or 2008 GPF. Her TES score placement matched her podium finish every time, with the only few exceptions being where she was arguably
underscored in components and got a
lower podium finish than her TES placement.
But how about other skaters? Other skaters this season, non-Olympic champions, have been quite generously rewarded in components when their performances appeared less than worthy. And as a matter of fact, their placement would have been different had they not received higher PCS versus other skaters who had a higher TES.
A few examples:
Patrick Chan: 2010 Skate Canada (TES placement = 3rd; actual = 1st)
Daisuke Takahashi: 2010 GPF (TES pl = 6th; actual = 4th)
Mao Asada: 2010 NHK Trophy (TES pl = 11th; actual = 8th)
Alissa Czisny: 2010 Trophee Eric Bompard (TES pl = 5th; actual = 3rd)
Carolina Kostner: 2009 Worlds, 2010 Olympics

eek
I tried to pick a cross-section of skaters, as I am not trying to single anyone out. This kind of thing does happen and not just for Olympic champions, and it is not necessarily bad (see below). But the evidence shows that it happens more frequently for non-Olympic champions than the current ladies Olympic champion, and there are more examples out there.
Just be clear: the skaters above had total TES scores (SP+LP) that indicated a different placement than what they actually ended up getting, which indicates that PCS played a significant part in positively improving that skater's placement. This does not
necessarily mean that the placement was unearned or that they did not deserve high PCS, it just means their placement relied more on the judges' determination that they deserved higher components than other skaters who delivered more technical content. It is very well possible that they deserved every point of that PCS, but that is a separate debate.
But my point is that every one of the skaters above has arguably benefited in terms of placement from alleged "reputation" scoring by the judges in terms of final placement, more so than Yu-Na ever did. Actually, the only part of the original argument that I can agree with is that Yu-Na has a reputation, period. But it certainly hasn't put her into medal contention by itself and it certainly is not more of a factor than for other skaters.
