So are you saying that the test pilots and engineers misinterpreted their findings during the test flights studying the high AOA envelope capabilities for the F-22?



Nope, someone has misinterpreted what the pilots and engineers actually wrote.


For instance - go to the
Wikipedia page, and it says:

The F-22 is also capable of maintaining a constant angle of attack of over 60°.[5]



Now, read the reference it gives:

The program has demonstrated outstanding flight characteristics at AOAs ranging from below –40 degrees to above 60 degrees.


and

High AOA envelope expansion testing began on 22 July 99 and cleared 1-g maneuvering beyond 60 degrees AOA by 8 September 1999


Neither of these quotes can be interpreted as sustained AoA - yet someone has.


Now, about the sustained AoA:

From the Air Force Association

David C. Schilling Award
The most outstanding contributions in the field of Flight
Lt. Col. David M. Nelson, Edwards AFB, CA
Lt. Col. Nelson is recognized for his tireless efforts, as the first F-22 operational test pilot, to improve the F-22 Raptor. He led the F-22 Combined Test Force in high-risk test sorties, expanding the aircraft's flight envelope. Colonel Nelson completed several first ever F-22 events to include sustained flight at negative 60 degrees angle-of-attack and the launch of an Advanced Medium Range Air-to-Air Missile.
