Sorry, I was off of work yesterday, and read your response late on Wednesday. You're making me feel really guilty by the length of your response, but I very much appreciate the work you put into explaining the logic. I typed out my reply right before leaving work, and realized later I never properly thanked you for your time and effort.



I imagine today will be slow enough for me to delve fully into the spreadsheet to pick apart the various formulas and how they work together. Hopefully, I'll be able to do that along with your descriptions so I can figure this out on my own without bothering you any more.
