If you look, F5 damage is only over like 200mph which only falls under a few catagoreys, like 'hospitals' and 'malls'. So this means something like the May 3rd tornado could be labeled as an F4 based off of damage alone since it really didn't take out a certain type of constructed building.

This is nothing new -- you've never seen an F5 that stays in a field! There's no way to assume winds that are beyond the intensity needed to create a certain level of damage... If 180mph winds can destroy a house, how do you determine if the tornado had 180mph or 210mph winds? This is the same issue as we've had with the old F-scale... If a violent tornado remains in open country, that tornado can't be rated F4 or F5... This is nothing new.
