<p>Perhaps someone out there reading this has an answer to this question.</p>
<p>From the data provided by USNWR BOTH UF and UC-Irvine have identical 6 yr garduation rates worth 16% and identical freshman retention rates worth 4%.</p>
<p>Yet when USNWR lists the Graduation & Retention Rank UF is # 44 but UC- Irvine is #40?</p>
<p>I could find no explanation in their explanation of their methodology.</p>
