As to some of the earlier comments Kim from Vancouver or London would definitely have a chance, a good one, to beat even the Kwan of Vancouver under 6.0 IMO. Irina Slutskaya at those Worlds managed only 5 clean triples, had a mistake, a sloppy performance that was below her season standards, and relatively weak presentation that is below both Kwan and Kim, and still won 3 judges, and had the higher technical marks. Kim even with 6 triples would get the higher technical marks no problem vs Kwan's 7. While I would agree Kim overall is a more devastating COP skater than 6.0, the judge under 6.0 would actually credit some of her very difficult triple-triples more than COP does. The judges would give huge value to her triple lutz-triple toe and reward it much more highly than a mere triple toe-triple toe and it would more than make up the difference of a triple loop. That is presuming Kim wouldnt even add a triple loop and probably land it if she felt it was important. Kwan when COP was introduced took out her triple loop as well, lol! Add to that Kim's jumps are much bigger and of higher quality, her spins are better, and her footwork are on par, and she generally skates with more speed, and she would easily win the technical mark. Slutskaya's much weaker (relative to Kim's best performance) 2001 Worlds performance even beat Kwan in the technical mark, presumably mostly since the judges felt a triple salchow-triple loop value over a triple toe-triple toe was enough to make up for all the other deficiencies of the performance. As for the presentation mark if Slutskaya was holding her own, Kim would be just fine there too. I actually found Kwan at the 2000 Worlds even better than 2011 but here Slutskaya with only 6 triples attempted, no triple-triple attempt, a big pop open, and one of the most generic Carmens I ever saw, still took marks off a perfect 7 triple, triple-triple, and again had higher technical marks than a skating with more speed and attack than I ever saw her Kwan, so again Kim at her best with her trusty mammoth triple lutz-triple toe combo I dont see being shut of a chance of winning even if she did only 6 triples, lol!
6.0 between Kwan and Kim both at their best and in general (keeping in mind the general consistency level of both and that most times they dont skate their best level despite being two of the most consistent skaters ever) would be very close either way though I agree. However that is the difference, Kwan vs Kim under 6.0 is a very close battle, but Kim at her best vs Kwan at her best under COP would be a blowout and Kwan would lose badly in that scenario. Notice how we are only debating who would win in these hypothetical competitions under 6.0, nobody even dares to propose under COP as it isnt even worth discussing. For Kwan to dominate under COP she would certainly have to avoid people like Kim and Asada at their best, and even Slutskaya at her best as it was already pretty clear their rivalry would have been very different under COP than it was under 6.0 (not that Irina was ever an easy opponent for Michelle even under 6.0). Even Cohen would have defeated Kwan many more times under COP than 6.0, and possibly Arakawa (although not too often only since she was a skater who dropped bombs on the ice 80% of her competitions), and probably some others too. I like Kwan alot but between her and Kim which skater would be more capable of dominating under both COP and 6.0, it is Kim easily, as Kim being a dominant force and winning most all competitions she skated her best under 6.0 (just as Kwan of course was under 6.0 and Kim of course was under COP) is much easier to imagine than the reverse being true for Kwan under COP.
Ito is very interesting to consider. I honestly dont entirely know how she would fare under COP, but I suspect at her best she would be almost unbeatable like she was under 6.0. That said one interesting thing is how they would score her jumps exactly. While I firmly believe she is the best female jumper ever, the COP rules require deductions for things like form flaws, so it would be interesting if she was still able to get the +3s on GOE. Personally I believe she should as the other qualities of her jumps more than make up for the leg wrap but with the COP rules I am not sure. Her spins and footwork in the late 80s were ahead of their time in difficulty as well, and she actually skated programs with more transitions than other skaters were doing for the time. Her spiral sequence was a fug miss but that is only one element.
As for the 1994 Worlds that was only close since Bonaly by far had a bigger name at the time. It was a joke it was even that close, but had Sato for instance won the bronze at the Olympics, it would have been 9-0 for her with the same performances.
Then you have the 1993 Worlds. Oksana Baiul landed only 5 triples, one of them two footed, attempted no triple-double combination even which was against the rules then, and still beat Bonaly who did 7 triples, a triple-triple, 2 triple lutzes, atleast 3 triple-double or higher combinations. Again like 95 not even close in jump quota, and Baiul still the viktor.
I mentioned this is my above post but when COP was introduced Kwan immdiately dropped the triple loop. Granted I know she was past her physical prime by then, but there is still no telling she wouldnt have done that even in her prime. She often missed that particular jump, just like Kim did, and Kim has done many very good triple loops as well. Part of the reason she dropped it was her hip problems in the late 2000s, similar to what Kwan dealt with later in her career; and then when her hip had gotten better, well there was just no reason to put it back by then. Although you also seem to be missing the point of what I mentioned earlier as well that under 6.0 judges looked as one of the harder 3-3s (the kinds Kim does in her sleep, and which Kwan could never do) as being worth atleast an extra triple (despite the crappy Bonaly still unable to win big events even with all that, but that is Bonaly). Something like a triple toe-triple toe was even worth about half a triple of extra credit in the judges eyes under 6.0 mind you.
I also think Kim's 2011 Worlds LP had potential to be her best program and performance ever artistically, and had she had the technical level of skating she often displays, her best ever all around. It is a shame she just wasnt fully ready for those Worlds. It is too bad we didnt see her more with Peter Oppergard, and to see even more of what he could have brought to her. Her few weaknesses like foot turnout and extensions were much improved under him. Kim is good friends with the Kwans too, so I was also surprised she didnt stay under the comfort of working with the elder Kwans husband, but maybe she missed home life in Korea by then, and being away in North America so long and so many yeras.
This assumes that the function of scoring rewards the events on the ice. As numerous posts have pointed out, this is sadly not always the case. In the most optimistic light, scores reflect a body of good skating work and simply note a desire to not punish a skater for 1 bad performance that season. In the less optimistic lens, scores reflect politics, preconceived notions about the skaters that refuse to allow the better skaters to actually win the competition, and simply exercising caprice to hold up things they think skating ought to be. I will say this: ordinals and 6.0 had the obvious advantage of being easily digested by the viewing public. Conversely, the other perverse advantage is that the audience might boo or ooh or ahh at abnormal scoring, but the computing of 2 scores and mentally trying to figure out where that would arrange that particular skater across 9 judges was nearly impossible, thus there was an air of credibility (legitimate or not) that accompanied that system.
