I didn't read this whole thread, because it started out like every other thread about match lists on SDN. Pre-meds don't know anything. Wonderful.
I'll say this:
If you know what residency you're specifically looking at, say, Internal Medicine, you can find the actual hospital ranks for this speciality (which change yearly), and look at the factors which are used in this ranking and determine which of these is actually important to you. You could end up with your own rank list.
You could look at the schools which "got" people into these specific hospitals for this specific residency program. I have "got" in quotes, because a lot of this is largely dependent on what you do as an applicant. Also, this is really just to give you an idea of whether more people who did pick this specific residency got into hospitals that are highly ranked for this specific residency. Still largely dependent on you as an applicant.
This is not rocket science. It also applies to fellowships. For instance, MSKCC is ranked number 1 in the US for cancer care. So it's not too much of a stretch to say that if you want the "best," you should come here. Best meaning you'll have huge name recognition. Of course, this list is iffy because one of the factors is hospital referrals which MD Anderson will always win at - because Texas - and the other is Magnet Nursing, which will not affect you as a fellow, but bumps a hospital up several points. By the way, the number of points allotted to each factor changed last year, so you'll need to watch these too.
But seriously, this is not "impossible to understand." And while, yes, to some extent the individual attributes and wishes of each applicant factor more into the list, it does get people thinking. And thinking is important.
IMHO.
