DBD,
You're on the right track buddy.
Listen to what the interviewer's tell you and address your weaknesses.
Common sense really.
If you're in charge of 130 or so people, then that's an EXCELLENT start.
ADFA and DE are assessed differently and for good reason. An ADFA candidate is generally still in year 12 and thus has not had the opportunity to gain general life experience such as that you're getting now. As such the interview board is likely to pay less attention to those kinds of issues. Each applicant is an individual and considered on a case by case basis. Thus you're all running your own race really. Be grateful for the feedback the DI/Psych gave you and use this wisely to maximise your performance next time.
