I actually talked to a girl from Hastings (not sure if she was on the admissions committee or not) about theirs cause I had heard a rumor that someone misfiled a form a few years ago which caused them to drop a good amount.
She didn't seem shocked and appalled that I would ask such a thing. However, if you don't have an actual question or interest about the ranking calculation, something to that effect, I think talking about it would not be a wise move.
