I modified the Custom Sheet a bit. I think this makes more sense to the User, you will only have to deal with the "Sheet Descriptors" when you rearrange the Bet Angel Sheet or the "Control Panel" Sheet

You, as User, will mostly be editing the "Calculation Settings" sheet. In Fact, I would hide the Sheet Descriptors sheet once you put this in production. The Sheet Descriptors sheet is edited by you as Developer or Coder
