Why wouldn't UPT student time be considered legit? If I have my complex and high-performance endorsements I should be able to log all of the time that I'm flying the T-6. Hell, according to the FAA, I can log all of the time that I am "sole manipulator of the controls" as PIC...even if there is an IP with me. Remember that the FAA has multiple definitions for logging PIC time...sole manipulator as mentioned above and "acting as PIC" which would be the IP on a dual flight. The T-6 doesn't require a type rating, however, the Tweet is a turbojet which would according to the FAA.
At least that is my understanding. Please tell me if I'm wrong.
