Awesome spreadsheet! Thank you so much. I'm going to fill mine out today.
Also, I save my settings to an old compact flash card (which has to be the only card installed to read or write the settings). I also connect the CF card to my Mac and copy the file onto my hard drive. I keep multiple versions on my Mac, each in a folder named with the date, so that I can keep a history of my settings in case my latest version somehow is corrupt or otherwise contains garbage settings. The files are pretty small.
