Tornadoes need a NESIS or ACE like scale that would account for not just the amount of damage but the areal coverage of the damage.
I don't mean any disrespect to the Ashby/Dalton, MN EF-4 it was an awesome tornado that I would have loved to catch if I was storm chasing. However, it really doesn't belong in the same class as something with a 170 mile path length that was a mile wide.
