This was addressed in
@chronicidal's
blog. The US News list always gives the top school a score of 100. So according to this ridiculous metric, Harvard med is at least 10% better than Stanford med (which scored an 89). And as
@efle pointed out in a previous thread, schools like UCSF and Hopkins are essentially given a B grade (an 84).
If you're curious about the individual scores, place your mouse icon
over the numeric rankings. You'll see that there's hardly a difference between the schools ranked in the 40s and 50s.
