That checks.
For promotion, they're looking at your ability to be a staff officer and beyond. The theory is: The "office related queep" is practice for that, and you're evaluated on your potential for staff and beyond. If you can't do CGO queep, how can you be expected to do staff queep? And nevermind the queep a Sq/CC and above sees on a daily basis.
Learn your jet and fly it well. Do that because lives are at stake.
If you want to be promoted check your boxes and do your "office related queep" well.
If you want to fly airplanes forever this probably isn't the right gig for you. There will always be younger, fully qualified pilots to replace you.
Those are the rules. They're not entirely fair, but they're clear as day. Get our your blue crayons, stay between the lines, and get promoted.
I see two problems with the current system:
1. There is far, far too much queep. I could elaborate, but there's no point.
2. The discriminators (PME, AAD) are based on no real ability or potential and serve only as self-highlighting eliminators for those that choose not to do them.
I'm in no position to fix the system. I can only play by the rules as they stand.
