This Category is for tornadoes that could have been an rated F5/EF5/T10-11 or equivalent but weren't due to do limiting factors, like not hitting the right structures with recorded windspeeds being in the F5/EF5 category or doing damage just low enough to be an EF4 or lower. (like the El reno 2013 tornado, Mayfield, Kentucky 2021 EF4 or Vilonia, Mississippi 2014 EF4)
