I would like to take up your challenge. I broke down Carolina scores from Worlds and replaced her missed elements with scores from other competitions where she completed them. The result shows that *if* both Yuna and Carolina skate their programs clean, the "large margin" you are talking about is not there anymore. Let’s assume Carolina went completely clean with the layout she had at 2013 Worlds:
In the short program, the scenario would be the following:
3Lo: 6.40
3T+3T: 9.50 (that’s the score she received for the same combination at Worlds 2012)
FCSp4: 3.84
2A: 4.63
StSq4: 5.60
CCoSp4: 4.07
LSp3: 2.97
TES: 37.01
With a mistake in the SP, her PCS score was 33.85. In case of a clean skate, she would probably receive higher PCS, I have to assume a number here so I am just going to go for 34.20 (she received 34.60 at Challenge Cup 2013).
TOTAL SP SCORE: 71.21
The long program scenario would be:
3Lz: 7.60
2A: 4.30
3F+3T: 10.30
FCCoSP4: 4.14
FCSp4: 4.06
3Lo: 6.71 (that’s what she received at Europeans 2013)
3T+2T: 7.04
3S+2T+2Lo: 9.03
CCoSP4: 4.43
StSq4: 5.80
ChSq1: 3.30
3S: 5.67 (that’s what she received at Challenge Cup 2013)
TES: 72.38
She had two major mistakes in the FP at Worlds this year and her PCS score was 70.69. With a clean skate, I expect her PCS would go through the roof and I don’t see why she would not match Yuna’s score of 73.61.
That would make a FP score of 145.99 and a total competition score of 217.20.
That should make it clear: Yuna still has the edge in this scenario, but the gap is not as big as some people here make it out to be.
Now IF Carolina upgrades her jump content in the SP and FP for next season (which I assume she would if she wants to go for Gold) and IF she delivers cleanly, she could very well match a clean Yuna. Carolina still has plenty of room to play around with her jump content especially in the FP, she currently repeats the two easiest triples (Sal and Toe) and only does one 2a.
I know that people will now cry out and say "but this will never happen, why are we even talking about this, Carolina will never skate clean in both programs". I agree - I think it's highly unlikely that Carolina will skate clean in both competition phases, she always makes some mistakes here and there. But we are talking hypothetically here, so why not look into it and play with the numbers. And if people say that hypothetically it's impossible for anyone currently competing to come close to a clean Yuna and that she would still win by a large margin, I think I just proved to you that this would not be the case.
Now, it would be interesting to see a break-down of Mao's program. Any volunteers to do that?
