I agree - and should have probably clarified. As you know I'm sometime prone to over-snarking my posts.
I think that the dataset, taken as a whole, may be useful. As I said, I think it's interesting to note that the "stats" tend to stay on top, non-medical EC's of any kind stay on the bottom, and recommendations become important at the interview stage.
Considering how important leadership and unserved community service is, according to SDN gospel, it's an interesting (and somewhat cynical) confirmation that this process is, indeed selective. But it's also highly numbers-driven.
But as a method of comparison, for "what's-important-after-you-get-the-interview" which is what this paper seems to be implying, it's useless. It's not as if you can change any aspects of your application once you've applied and been invited.
I guess I'm just irritated since the two tables are, as I said, exactly the same from a statistical standpoint. When your standard deviation is 50% of your entire measurement scale, there's something wrong with the experimental design.
