When you are calculating and itemizing I would take into consideration that you have a greater chance for making rank as an active pilot. You can not expect to get command as a non-active pilot. Depending on your position and stage of your career you may not think command is likely at this point, but that's what a lot of guys think early in their careers. I've known guys who got out to go to the airlines and then after 9/11 were furloughed; many came back on active duty, and some have even gone on to command active duty squadrons in combat. Your OPRs are probably full of the standard "Walks on water" bullets, and I'd say with that kind of material you can make a good case for having had a very good shot at sqn command. From there you can make a good case for O-6. Who's to say you wouldn't have made general? But that possibility doesn't exist if you can't fly, and you can't expect to compete with a logistics officer this late in the game.

So I'd make an issue of what you could have earned over a 25-30 year career. If that doesn't hold water then the other fork in the road is what you would have made after getting out when you didn't get command (because it's "What you always dreamed of and worked toward." and you didn't command of a flying squadron you would have pursued commercial aviation) and what you would have earned working to 65 for a major or 70 for a corporate. Just my $0.02.
