To your 1st paragraph, I would say that proves my pointAs has been said, Trenary and Thomas are World Champions, Chin and Kadavy are World medalists. No U.S. lady save one on one occasion over the past 15 seasons has medaled at an Olympics or Worlds.
CF DO matter because that was the context in which those women competed. They won World and Olympcs medals under the competitive format as it was then. CF are another variable in the equation for those women and they won and/or medalled at World events under those criteria. Winning then, required, in part, a different skill set. So yes, CF DO matter, particularly to the argument you were trying to make which is comparing Trenary, Thomas, Chin and Kadavy to the current generation of U.S. ladies. They are not comparable. That group of women medaled and won under the established criteria of their time. The current generation does not.
Your argument about fields being more competitive since 2006 is sort of true...some times...fields go up and down arbitrarily from one quad to another and citing Miki Ando as some criteria for 'level of greatness' for an era, doesn't help your argument. And the comparison isn't apples to apples, either because, again: CF, which means that there were some excellent skaters at CF that needed to be contended with, as well as excellent free skaters. So yes, I would contend that you are making broad generalizations about a particular set of women skaters from the past (Trenary, Thomas, Kadavy and Chin) without acknowledging the particular era in which they skated and the particular set of competitive criteria under which they competed, which are not the same as the U.S. women of today are competing against.
To your 2nd paragraph, CF are irrelevant. Prior to IJS, all women were competing with CF and the US women beat them a lot of the time even if they made mistakes. Under IJS, everyone is competing under the same system and they don’t win. Why? because I believe the world has improved
Mike Ando is a x2 World Champ, did the 1st quad, and bested Yu Na and Mao. No US woman at the time could beat that. IYO if you feel I am generalizing. It’s OK
