    Oh yeah, those are excellent results! I apologize for misunderstanding. I
    read through that message so fast earlier that I missed the bottom line. I
    guess the only part I'm puzzled by now is why you agreed with Lord Kelvin

    misunderstand that, too? Were you agreeing with his assessment or not?
