Meteorologist John Robinson with the National Weather Service in North Little Rock issued an explainer today on why the Vilonia tornado earned an EF4 rating rather than the top rating of EF5. UPDATE: He's also provided information about the death that occurred when a door failed in a "safe...

Will repost this because it came up on another forum. Just so much crap.
The second paragraph is, in my opinion, one of the main sticking points, because as I have explained before the implicit intent of the Fujita scale was to rate primarily by using a very common structure. Robinson is obviously not going to admit if he was 'the person', and that fact it got through rather than being contested is a sign of implicit agreement from the others. I wouldn't be surprised if it was someone else like Marshall though. Either way the solution is very simple, which is to move the threshold to 200 mph.
There is an obvious bankruptcy in the idea that a house has to be of somehow 'superior' construction to get EF5 when apparently the standard of construction to achieve the 'expected' value is extremely rare. As a matter of fact it obvious to anyone in the real world that a house which has 'full load path' with straps and hurricane clips etc.
is of superior construction.
The main problem here is not anything to do with the science or engineering, it is the groupthink that exists amongst the people who actually have the power over these things. This is a pretty normal thing in power hierarchies really, but it comes with the important implication that change has to come from within that system. That change might only come when the current lot retire (or die) and if they are replaced by people who think differently.
