nsplayr, yes, that was my situ. Finished my ADSC and punched a few months after. I got PTDY, but I took some of it before my final out. who knows if it was right or not, but when scheduling my final out date finance even asked if I was taking any PTDY in conjunction with terminal.
BTW, can't find any references in the A&FRC reg (36-3009) about how separatees are coded. But the AFI was more recently revised, so the leave guidance could be outdated...
