Both the Andover Tornada in '91 and the So. Wichita - Haysville Tornada in '99 have been described as F5's, but are generally accepted as F4's. Same with the Heston 'nado a couple of years before that. I am talking about a 40 mile square area that got as many as 3 F5's and a couple of F3's in a decade.

The '91 F4/F5 Tornado came within less than a mile of flightline full of B1's
