This happened a lot with me in the T-34. I just assumed if I was the designated IP (the one giving an event, even if it was with another instructor), aircraft commander (signed for it) or solo, it is PIC time.

If I was receiving training (recurrent, Stan check, etc) or otherwise wasn't sure, I counted it as dual received.

In the end, if you can logically explain it and are consistent, I doubt it will matter. Most mil guys, especially training command instructors have enough time in each category that it isn't an issue.
