Still bored, awake and am now into "night before an event" nervousness mode.
So I updated and re-uploaded the two files listed/linked to in the original post.
The Excel xls file is definitely more useful/understandable "out-of-the-box" than the csv version. Other than the file format limitations (csv strips some formatting and a few functions) they are "identical".
Feel free to download & try the new file of your choosing.
Also, feel free to curse me tomorrow as I am riding for not including this or that idea/thought you had or some "bug"/broken formula_or_reference you may have found. I won't hear you, but feel free to do so.
