Second on what ThreeHoler just said about stats not meaning much because in the end he is right. That being said I was told 18% of the '04 board were school selects and the Air Force target for the '04 guys is 33% attend school in-residence. Use the stats for what you want but I am '04 guy who is not a select, I am planning on working hard and hopefully getting lucky. The good news is if you never go to school in-res and check all your boxes you may be able to make Lt Col with about half the work of the bros that go to school, staff, and command.
Edit: sorry I missed the original question about AAD, no idea about that one.
