Of course... sorry.

I have a splitting migraine right now. I agree, that is very odd. Just another little idea, but along the same lines of thinking, I wonder if a category six rating would be appropriate. While rare... perhaps happening only once every decade or two, we have a storm that gets around 170-190mph. The destructive power of such a storm would be far greater than the 155mph wind requirement.

EDIT: Actually tera... I was thinking, and the numbers have rhyme and reason to them. A category four is literally a hundred times more destructive than a category two. This is because a winds destructive force increases exponentially. The brackets are calculated around the concept of what will destroy a certain type of structure (ie, a breaking point)… so that is the reason for the odd numbering.
