If the guard/reserves interests you, I'd highly recommend checking out https://milrecruiter.com/afrc-uft-selectionboards/. My buddy that was not selected last year applied this year to reserves and found out he was picked up weeks later. Their next application is due 31 Dec (five days from today). There is an option to apply unsponsored with your PCSM being above 90. There are a couple other things too (no ETPs and willing to fly any tanker/transport aircraft with the reserves).
Im not too keen on the process, so I don't have all the data, but I have explored the option as a backup plan. A few things I do know is they hold a board in October, January, April, and July, and results are typically pushed out the same month the board convenes.
Good luck, dude! I hope everything works out. Sounds like you've been working your a** off to get a slot!
