If I’m watching gymnastics as a casual fan, I have no idea whether the judging is fair/consistently applied. But I know there are things that the panel is looking for, and that I wouldn’t necessarily recognize them. I rely on commentators onscreen or here to tell me when things are rotten in Denmark.
I don’t know why casual skating fans are any different, ie, if they wouldn’t just think that there’s more to it than they know and listen to at least some of the commentators who explain it and pass on what the technical panel is doing and how the scores are changing, or not. It hasn’t been that many years that the announcers admitted that they were given access, not that they were spying on the screens, and that they’ve been willing to pass on the info.
