Which is why I have mixed feelings about the Enhanced Fujita Scale. Not to slightly criticize the N.W.S., but sometimes, people who are surveying the damage don't look at it closely enough and it gets rated an EF4 when it should've been an EF5 (or at least a High-end EF4)While I do believe EF4 was the right call for Winterset, I also feel the wind speed estimate of 170 MPH was too low. At its peak intensity, it swept away an anchor-bolted house and cracked part of its foundation in the process. While the cracked foundation likely resulted from a preexisting weak point known as a 'corner pop', still, foundation damage like this is NOT something I tend to associate with low-end EF4 tornadoes. I don't think the other contextual damage (debarking, scouring, vehicle mangling, etc.) was EF5 worthy but a wind speed estimate around 185-190 MPH would have been more appropriate imo.
