I am active duty Navy and my wait time was about 2-21/2 months. Submitted in July and got final word in October. I think it varies between active duty folks and civilians, plus timing is another factor. If you package gets in right after a board finished delibrations, you will have to wait till the next convening date, however long that might be and of course, if your package is received just before a convening date then I guess you don't have to wait for too long.
