IM, no one of us should dare to rip you for such hard work, DD, and having on your thinking cap to the nth degree.
Fabulous piece of work, whether your deductions are totally accurate or say, even close to the mark...Hell of a job Whaz...Kudos!
It will be most interesting to hear the commentary from the board, but I think you are way ahead of the tribe here because of the major effort and suppositions, based on what was shown in your reporting.
Again, excellent effort on all our behalf as we try to connect the dots of what's behind the curtain...
