The last couple of years, I've looked a little at the aggregate data for peer and lawyer/judge assessments for each of the US News tiers. This time I'm interested in changes by tier over the last couple of years, so I report US News 2007 as well as US News 2010 data. I'm posting a little here, again. More shortly.
