Although the OBO proposal is intended to eliminate flip-flops in the standings as the event is in progress, the simulation showed that under OBO there still would have been a total of twelve sets of skaters involved in flip-flops in eight of the fourteen competition segments. There were also at least four other instances of circular "who-beats-who" relationships where flip-flops might have occurred had the skate order been different.
Here are more details of the instances of actual flip-flops:
The first group consisted of Robert Grzegorczyk, Laurent Tobel, and Michael Tyllesen. In the simulation, Tobel was initially ahead of Grzegorczyk with a greater number of "wins", but Tyllesen's marks put all three skaters into a tie on "wins". At this point Grzegorczyk was ahead on "judges in favor" with Tobel and Tyllesen tied behind him. Later Tyllesen moved into a tie with Grzegorczyk instead, and finally wound up placing between Grzegorczyk and Tobel.
The second group consisted of Zhengxin Guo, Szabolcs Vidrai, and Markus Leminen. Vidrai was initially placed ahead of Guo on "wins", but as Guo "won" the head-to-head comparison with Leminen and Vidrai did not, this gave all three skaters the same number of "wins" and the tie was broken to rank them in order Guo, Vidrai, Leminen.
E.g., before Shmerkin:
Wins JIF 10. Margus HERNITS 5 41 11. Markus LEMINEN 4 39 12. Ivan DINEV 3 41After Shmerkin:
Wins JIF 10. Margus HERNITS 5 45 11. Michael SHMERKIN 5 41 <=== new 12. Ivan DINEV 4 47 <=== changed 13. Markus LEMINEN 4 43 <=== changed
The first again involved Joseph & Butler and Clements & Shortland, this time in a three-way near-tie with Dominique Deniaud & Martial Jaffredo. Although Clements & Shortland had originally been placed ahead of Joseph & Butler, they finished two placed behind them.
The second involved Kati Winkler & Rene Lohse, Margarita Drobiazko & Povilas Vanagas, and Irina Romanova & Igor Yaroshenko. Within this group of three couples, Winkler & Lohse switched places with Drobiazko & Vanagas, and Romanova & Yaroshenko went from being tied for the lead to being third.
The first three of these competitors to skate were initially ranked like this:
Wins JIF 5. Joanne CARTER 8 63 6. Zuzana PAUROVA 7 64 7. Angela DEROCHIE 6 61 <=== newPoth scored "wins" over Paurova and Derochie, but not Carter, creating a three-way tie on "wins":
Wins JIF 5. Diana POTH 8 69 <=== new 5. Zuzana PAUROVA 8 69 <=== changed 7. Joanne CARTER 8 67 <=== changed 8. Angela DEROCHIE 6 64Next, there were some further fluctuations in the number of "Judges in Favor":
Wins JIF 5. Zuzana PAUROVA 9 77 <=== changed 6. Diana POTH 9 76 <=== changed 7. Joanne CARTER 9 74 8. Angela DEROCHIE 7 69 9. Julia SEBESTYEN 6 60 <=== newKulovana then received marks that gave her a "win" over Poth but not Derochie. This caused Poth to drop out of the 3-way near-tie situation with Paurova and Carter, and also put Kulovana and Derochie into a tie.
Wins JIF 8. Zuzana PAUROVA 10 83 9. Joanne CARTER 10 79 <=== changed 10. Diana POTH 9 81 <=== changed 11. Lenka KULOVANA 8 74 <=== new 11. Angela DEROCHIE 8 74 <=== changed 13. Julia SEBESTYEN 6 62Next, Leray got a "win" over Derochie but not Kulovana. This had the effect of breaking the tie between Kulovana and Derochie, and moving Derochie into a near-tie with Leray instead.
Wins JIF 9. Zuzana PAUROVA 13 106 10. Joanne CARTER 13 101 11. Diana POTH 12 103 12. Lenka KULOVANA 11 95 13. Angela DEROCHIE 10 93 <=== changed 14. Marie-Pierre LERAY 10 91 <=== new 15. Julia SEBESTYEN 8 80Finally, Mojca Kopac also scored a "win" over Derochie (but not any of the other skaters in this group), which caused Derochie to drop behind Leray.
Wins JIF 11. Zuzana PAUROVA 14 116 12. Joanne CARTER 14 109 13. Diana POTH 13 110 14. Lenka KULOVANA 12 103 15. Marie-Pierre LERAY 11 99 <=== changed 16. Angela DEROCHIE 10 97 <=== changed 17. Julia SEBESTYEN 9 87 18. Mojca KOPAC 9 82 <=== newIn short:
The first group involved Julia Sebestyen, Silvia Fontana, and Marie-Pierre Leray. Sebestyen was initially ahead of Fontana on "wins", but when Fontana scored a "win" over Leray and Sebestyen did not, all three of them were thrown into a tie on "wins" that was initially broken in the order: Leray, Fontana, Sebestyen. Later Fontana pulled up into an absolute tie with Leray, so that she finished two places ahead of Sebestyen.
The skaters in the second flip-flop group were Elena Sokolova, Diana Poth, Yulia Vorobieva, and Tanja Szewczenko. Sokolova initially led Poth on "wins", but since Poth scored a "win" over Vorobieva and Sokolova did not, we once again had a situation where three skaters were thrown into a tie on "wins". At this point, Sokolova remained in the lead with Poth and Vorobieva tied on "judges in favor". Later, Poth dropped behind Vorobieva, and then back into an absolute tie. Finally, Szewczenko scored a "win" over Poth but not Vorobieva or Sokolova, which once again dropped Poth both of those competitors on "wins", as well as behind Szewczenko on "judges in favor".
