I do know at least 1 home at Cambridge Shores was well built, but as for the rest im actually not sure of. The DAT tool kit only has a couple of homes. Considering radar had pixels of 170-190 mph im not too upset about high-end EF4 for that area.The contextual damage at Cambridge Shores was most certainly EF5. Trees either completely debarked or shredded to near or at ground level, multiple homes swept in addition to severe debris granulation. Photo below.
The Bremen home wasn’t just a block home. There was a portion around the storm shelter that was a concrete foundation and was well bolted. That portion was swept to its slab. There is literally a home of similar structure that is still in the EF-Scale manual for EF5, thus a home (if well anchored) can be rated EF5
