Actually, I did want my questions answered. It's just like when a F/O walks up to the briefing with a new Capt. The Capt tries to assess who he is flying with, that person's relative experience, and get a feel for their competency. I am not stuck on any particular agenda, I wanted to see the level of actual knowledge for some of you keyboard commandos. And, the bonus would be, maybe I would get a new nugget of info that I could cross reference for it's validity and learn some more. As one who has read journals put out by the American Physical Society, the American Academy of Science, and various non technical science publications for decades, and one who has had graduate courses in statistics, I find these discussions quite amusing. They surely reinforce the idea that the less I know the more sure I am.
