Side note - I will say nice analysis on your part here. I truly expected this to tighten up more rapidly then it did. In this manner, I am happy to be wrong and wanted to say nice job on your analysis.
That withstanding, seeing observations, I do wonder if the energy of the storm and category 1 winds across a much broader area for an extended period of time actually is causing more damage than a Cat 3 at Landfall. I guess therein lies the two edged sword.
Either way, a learning experience and something to tuck into the back of my head for the future.
