What difference does it make? First and second pilot time aren't tracked by anybody but us are they? As a RAG IP (the only time this ever mattered for me) I would just have my student give me a .2 or so. Whatever. Do airlines or the FAA care?
From what I've read here, if you're not AC, but you have FPT logged, you can count it in your favor for the airlines. I, personally, don't care, hence why I just split it down the middle in the fleet. In the TRACOM it's a little different, but otherwise I'm w/ you.
