Thing is, the inflection point is training completion. If the member wants out of the AF ASAP, it'd be more advantageous for him/her to start the ADSC clock by finishing UPT than it would be to get banked like in the 90s, awaiting initial training while in some other AFSC. Frankly, I'm surprised big blue hasn't in fact considered 90s styled banking in lieu of starting these people's ADSC clock.
Retention at this point is stipulated as a non-concern for big blue. It's not a business accountable to anyone but congressional pork, as such senior management can afford to be perfectly price-inelastic when it comes to the question of retention.
