Doesn't it seem a little limited when often the only feedback you get is whether you got recalled or what place you got?
Yes, but also no.
In my view, contest results have value because they are the closest we can get to
objective feedback. The price we pay for that "objectivity" is a total loss of descriptiveness--there is no feasible way for us to understand
exactly why another couple was rated better than us. Not even this...
I guess really the only way to follow up is to pay a judge to give you coaching and ask them directly about their opinion?
Following up with a judge doesn't actually fill this gap, for a couple reasons. First, you will at best understand only one of the votes on your card, and your result is the aggregation of many. Second, an individual judge's mark isn't a measure of your absolute skill; it is a snap evaluation where you fall in the hierarchy of this specific slice of the field at exactly the time they were looking. Only in aggregate does the inherent noise of this smooth out into something we can draw conclusions from. I think about it as a sort of "data sample", where each individual point is not really valuable by itself.
Nonetheless, I do think that studying with judges is a good idea, because "buying a mark" (to give it the crassest label) is a real thing. But I wouldn't do it as a way to make my competition feedback more
descriptive and explanatory--for that, I rely on the home-base coaches who know me, know the roadmap ahead of me, and have personal investment in my success.

Bottom line: we need many different kinds of feedback to best guide our growth. Variety is important, because the different feedback mechanisms are useful in different ways. Competition feedback is valuable because it provides an insight we can't get any other way, but it can't tell us *everything* we need to know. We should remain wary about over-reading or over-relying on it.
