The only way to do that is to re-mask PME and AAD. Trying to tell a guy that he needs to focus on flying and that should be priority will always fall on deaf ears when so long as you pass your annual checkride (and don't hook a no-no) flying has ZERO bearing on your career progression. It's like the battle against firewall 5 EPRs-- nobody is willing to do it because nobody wants to take that first step and risk burning their people, and understandably so. I look like shit on paper because I flew the line and deployed my ass off for the first 3 years on station. Aside from some faster-than-normal positional upgrades, I've really got nothing to hang my hat on when it comes to shoe centered stuff. I haven't won CGO of the quarter, I haven't planned the christmas party, I haven't been an exec or any of that stuff. I'd be ok with it, if I didn't know that shitty pilots are in a better position because they have checked all the shoe boxes. It doesn't matter that they can't even tell you which section of the TO covers emergency procedures, they're the CGO of the quarter! The fact of the matter is that everyone is assumed to be a good pilot (even though that is clearly not the case) and commanders have come to rely on what should be tiebreakers to break ties that are FAR from existing.
Thinking that PME and AAD are going to be masked is a pipe dream though-- the shoes will never allow it to happen. If the promotion board rack-and-stack were actually based on the contributions of the individual to actually accomplishing the AF mission, the shoes know they will continually be eating the table scraps of guys who have forgotten what the color green looks like. PME and AAD and bullshit meaningless awards are the only way shoes have a chance of competing with guys who make their living doing what they were actually hired and trained to do, and doing it DAMN well.
Part of the "overmanned" fallacy is that all those dudes out flying the MC-12 are still on YOUR books. So if your unit is allocated 20 pilots, and 5 are out flying MC-12s, you are showing 100% manned on the books, while in reality you only have 75% of bodies on hand, before you even start to count DNIF, R&R, leave, etc. It's bad, and I doubt it's going to get anything but worse as the years progress.
