<p>Addenda:
1.) I believe that all five schools are aboove 85%.
2.) I believe that Duke gets a smaller percentage than they do.
3.) I do not believe (but will back down if shown) that they claim to be the top five. If they do claim this, they are incorrect.</p>
<p>In any case, of those five, only one is on your list of four, which is what I initially wanted an explanation for.</p>
