To be fair, the tornado was a very narrow tornado. Which is good and bad. Think of a figure skater who is spinning. If their arms are extended, they spin slowly. Once they bring their arms in and are compact, they spin faster.The only thing I don't like about some of those vids is they make the damage path look so narrow, when in fact at ground level it's a completely different story.
So if the tornado was wider, the wind speed likely would had been lower, but more buildings may had sustained damage. But since the tornado was compact, the winds were much stronger leading to catastrophic damages, but only in a narrow path.
