I don't think there's much of a story there. FS is a subjective sport? OK.
I don't think a mere appeal to subjectivity will carry water at all here. The criteria for things like jump ratification, jump GOEs, penalties for mistakes in jumps, are all clear-cut and whether they are fulfilled or not is readily discernible, even for a layperson, if they bother to read and understand the rules. The rules for calling spin and step levels are clear, and should be able to be applied consistently across many different FS comps by the tech panels. But they weren't applied consistently in Sochi compared to the World's just after. Look at the difference of StSq levels awarded for the same programs in both competitions.
I think a far more plausible explanation for the Sochi tech panel's and some of the judges' apparent disregard for the rules is something along the lines of the story I gave. I don't think any of their perceptual faculties were malfunctioning the two nights of the ladies' event, do you? If they had wanted to apply the criteria like they allegedly were trained to do, I believe they could have and we'd have had a different ladies OG Medalist.
You asked me for what I thought would explain the SP results so I told my story. I guess we'll just have to agree to disagree.
