<p>I’m not sure the differences in historical rank prove your previous statement, namely that
“As I said before, Duke is a more or less bigger name than Columbia, Upenn, UChicago and some other peers, especially in east coast.”</p>
<p>Also, I haven’t run the numbers, but I imagine if you include years 2008 - 2012, where duke remained in the 7-10 position, Penn remained in the 5-7 position, Columbia eventually jumped up to #4, and Chicago eventually jumped up to #5, the schools are even closer in terms of their historical rank.</p>
