Senior Raters and the FSS have always gotten the info early
both have letters to draft, documentation to update on surfs, etc
group and squadron commanders or equivalent find out a few days later. Individuals have always found out by COB prior to release date.
Statistics don't generally come out until public release date. Sometimes a senior rather Or base might try to figure out statistics based on their persons and the list, but it's only accurate to a certain degree.
