My thoughts about the two judging systems, B/S, and Sarah Hughes:
(1) The new judging system, with its overpenalization of URs, definitely appeared to have the goal of addressing a major criticism of 6.0: bad jump technique was not penalized frequently and consistently enough. However, it's not true that wrong edges and cheated jumps were not penalized before. They were simply penalized less than now. Skaters with deficient jump technique such as Amber Corwin, Jennifer Robinson, Nicole Watt, Silvia Fontana,
(and Sarah Hughes as well) were visibly marked lower on the first mark. I'm sure that the whole ice dancing debacle that season, with D/V being screwed over, contributed to IJS. However, I personally prefer 6.0 ice dance programs.
(2) The new judging system has closed up a lot of room for score manipulation, but not completely. I never made the effort to give levels to B/S and S/P in Salt Lake. But I imagine the politically motivated judges would have done what they could to keep the two pairs close together by inflating S/P's GOE and PCS, or even by inflating levels on elements.
(3) According to my memory, URs were already explicitly penalized as early as 2005-06. I remember clearly Shizuka getting shafted out of GP Final by underrotating the flip in the short program at both of her GP events. I also remember Alissa Czisny landing a cheated 3lutz-3toe and only getting credit for a 3-2.
Finally, I'm still confused why people think Sasha Cohen "fell twice" in the Torino LP. All people have to do is read the protocols to see that she only fell once.
IMO, what makes Irina seem bitter is her idea that she could have been a five time World champ. I would like to know which World titles she thinks she should have won (besides 2001)
I definitely think could have been four-time World Champ and Olympic gold medalist if she was a better competitor. If she had, for instance, the consistency of Zagitova last year, she would have most likely won Worlds in 2000 and 2001. With her difficult tech content, the judges seemed ready to place her ahead of Michelle if she delivered (not sure I agree here, but that's the way it was). Unfortunately, Irina took herself out of contention with mistakes.
