How long does a Class lll flight physical take for Ft Rucker to approve and send back?

How long does it take for a Class lll flight physical to come back from Ft Rucker? I'm trying to reclass to a 15W (Drone Operator) and hoping it's approved and ready for pick up after this 4 week training exercise so I can take it to retention and proceed with my reclass request. The flight surgeon couldn't give me a answer than "I've had packets come back fast and some noy so fast really a couple of days to 8 weeks" I'm just hoping someone can give me a better time frame is all.
