You don't reading comprehension, do you? Did you miss this part, that set the qualification of "worse"?
So the parameters were cities being hit by deadly storms. Not simply most power recorded anywhere on the track of the storm. By this measure, what catchall was actually asking, no it was not really far worse than many other storms in the past, and even from measured pressure it was 7th when it made landfall. Strong storm sure, but not the strongest ever that made landfall, which was the original comment/question.
The question was still is this storm worse. Not did it do more damage, effect more people, blah blah blah.
An argument can be made that the intent was "I see Florida get hit with deadly tropical storms just about every year." Catchall may have meant 'compared to the damage of other storms that usually hit southern states, is this storm worse'? He could also have meant 'compared to other storms, was this stronger', 'was this really the first cat 6 storm we've seen?' or even 'does the name irma worse than katrina, sandy, harvey, or andrew'?
But none of that is written, is it? There's a few observations, and a question. Nothing connecting them, there's no data points he's specified, or a bar of which to judge, or even a timeline of when to look at the bar.
I don't know what Catchall considers worse. Whether he's trying to discern which state needs his donation more, or asking is climate change making for stronger storms, or even trying figure out what he wants his/her romantic partner to call his/her private parts.
