It would need to get to 201 mph. The floral shop is the 195 mph DI and was "partially swept away" per JAN. I'm pretty confident that we'd have a 5 if that was cleanly swept.Would need to get 205 MPH though.
As Robinson obliquely referred to (probably because he was responsible) fixing the EF5 threshold at 201 rather than the 200 the review indicated was completely political.
It's not the biggest problem by a long chalk but acknowledging and changing it would help show a better, more scientific attitude.
