If you think I have time to research this you're wrong. I offered an opinion. My opinion, based on my experiences and my knowledge of the industry. I do not claim to be an expert on the issue. I specialize in the human side of disasters, not the technical. I am not prepared to provide a dissertation, nor do I care to. I'll leave it to you to pull up websites if you're so inclined. (Because we all know every chart, every figure, every report, and everything published on the internet is well-researched and unequivocally true).
Carry on.
