Perhaps Mike can put Charley in as a Cat IV. Mitch was a 5, yes, but not at landfall. Andrew, 10 years later, was reclassified, but was a marginal 5 at best (not making light of that fact, he was the mother of all canes, at least in terms of being the most expensive). Ivan was also a 5, but not at US landfall, and he danced around every piece of land on his way to the US (except Greneda). Gilbert was a 5 when he struck the Caymans, so perhaps he would be a better example. And of course, there's always Camille.
