The switch from F5 to EF5 in 2007 raised the wind-speed threshold for the top rating from about 261 mph to 200+ mph. But engineers also raised the damage bar considerably — for an EF5 rating, damage-indicator scoring now requires evidence of "well-constructed home swept clean from slab" or equivalent.
The result is that some tornadoes that would have been rated F5 in the old scale are now capped at EF4 because no well-built structures were in the peak damage path. Since 2013 there has been an EF5 drought — nearly 10 years passed without a confirmed EF5 in the US, ending with community debate about the calibration.
