We had guys turned away from FedEx for indicating they had "completed" an FEX written when in fact they meant they "…was fixin' to have it…." That didn't work out so good for some.

I've had clients offered pop up classes when others fell out. You'd hate to say "uh…sorry…I can't REALLY be there on that date, because I gamed my availability an extra 60 days to get the phone call sooner…"

You might just expedite your interview into a being terminated before you ever hit the property. My professional recommendation is take your separation date, add the terminal leave, the permissive TDY, and any comp days your command might allow. Lean forward, but do not lie. Integrity issues will keep you off the property faster than any other single issue.
