No offense at all, Mark.  This is good stuff  :-)
I would not have taken the time to do the timing test, since I am working on
deadlines for my business.  The main reason I went through the calcs is that
I wanted to know, and the reason I did such a detailed analysis is that
others tuning in could evaluate it for their purposes.

Contributing to the list is something I really should not be doing at the
moment, but then again, learning more about Rev will pay off quite well
