First off, Mike is right, this should not be a tit for tat situation. It should be about disseminating the best information.
I understand you are getting valuable advice and that is great. However, you have yet to understand a "line number". That GPA does play into the scenario. HOWEVER, it does not play into the game of OPR (promotion boards). The higher the GPA the lower your line number, the lower the number the earlier you pin on. The reason this Lt Col is asked about his gpa is because it is tied to his line number, it is not on his OPR! This is akin to ROTC grads knowing their DOR.
Now let's put that in perspective, do you actually believe that if they promote 100 O3's a month, that if you get promoted 1 month, 2 months, or even 4 months later you have an edge 4 yrs down the line for promotion to O5.
Bullet went to sister service as an O4 for PME, out of a class of 60 (the entire class was @ 600), only 15-20 were AFA grads. Additionally, out of the 60 AF officers, maybe 15 were flyers. Out of the 15 flyers, maybe 6-8 were fighters. Out of those 6-8 fighters, I only recall
ONE AFA grad.
Don't bank on the AFA commission to be a safety net.
Next, everyone agrees engineering opens doors, regarding flying, but I think you are putting the cart before the horse. You can graduate with a 4.0 from the AFA in engineering and still BUST UPT. There is no true equivalence that a UPT student with an engineering degree will be the #1 at UPT. Like I said before it is how you handle the stick.
If you want TPS, then without a doubt go Engineering, but if anyone tells you that you can't make it to the top without TPS, then they are lying.
BTW, I would love to see you have this conversation with Gen. Gould...you know the SUPE of the AFA...FYI...he is a 1976 graduate of the AFA with a BEHAVIORAL SCIENCE DEGREE.

Or
General Mark Graper who graduated with a degree in International Relations AFA class of 80, he has over 2600 Fighter Hours
http://www.af.mil/information/bios/bio.asp?bioID=8310
Or
General John Hesterman --- AFA grad International Studies AFA class of 83 ---2100 Fighter Hours.

Or
General Norman Seip who graduated with a degree in History from the AFA in 1974. He has over 4500 Fighter hours.

Now, I love OBD, but check out Brig. Gen Robersons career...he was an AFA 83 grad in Engineering.

Notice something? He graduated with MAJOR GEN Hesterman. Last time I checked a shoulder flip OBD loses to Hesterman. OBD was engineering, Hesterman was not. Both flew the F-15E. Under your premise OBD should win the shoulder flip based on his degree. (Shoulder flip is when you cover your rank on your shoulder and the one with the higher rank exposed wins).
Finally, Bullet and I had 3 friends who went to TPS, NONE were AFA grads, they were all ROTC. One did get to complete his dream of being in space last summer, after 25 yrs of working for it. YEP...25 yrs. He was commissioned in 1984, went to space in August 2009. He retired in October 2009 as a Col.

All of us get your point that the AFA is the "Little Engineering School in the Rockies", yet, to imply that your best option for career progression is to go engineering is hurting posters. Only one of these Generals received a degree in engineering from the AFA.
