Applying a clear coat where one isn't accurate isn't "going the extra mile."
My comments are based on what Jantrix said earlier, and I think he is correct... "shiny" catches most judge's eyes, and many (not all) judges favor the miles-thick shine over a model that may be less shiny, but actually correct. So if it's true that most judges like the shiny stuff, and they base their awards to a large extent on that (as Jantrix pointed out, not me!)... if that is actually true, then it's a fact that many judges are doing their job poorly.
