The spreadsheet with the FY24 promotion board zones can’t be posted publicly, but you can find it here as long as you have your CAC card:
It is posted down on the right side. Just hit use the find function and search for “lineal”.
P.S. If you are Medical Corps, you actually don’t need the lineal list to find out when you are in zone. Because the Medical Corps is DOPMA exempt, you can just use chapter 2 of the Promo Prep to figure out when you are in zone for promotion.
