While I respect people like Simon Brewer, their tendency to hew closely to the “official” line and procedure in regard to DIs is troubling. For example, the tweets highlighted above are remarkably reluctant to explicitly state that the clearcut EF5 damage is, well, EF5 damage, but instead sides with “at least high-end EF4.” At this point, people need more courage to call a spade a spade and not waffle with qualifiers such as “borderline EF4/5” or “high-end EF4
or EF5 damage.” The contextual DIs
clearly support EF5, not “high-end EF4.” This is
not a “borderline” case, any more than Chickasha, Goldsby, Vilonia, Chapman, et al. were “borderline”: it is
blatantly obvious. The UK research facility alone is
well into the EF5 category, as is the trench-digging, the destruction of well-built brick buildings in downtown Mayfield, the ground scouring, the extreme granulation, the damage to vehicles, etc.
