If you signed for it, the entire flight is PIC regardless if you were in the seat. That is the only PIC I claimed regardless of the funky formulas some companies say you can use. It is the most conservative and easily defended. I found it extremely tedious to keep all my apps updated using each companies formula and I kept finding mistakes so I reverted to the most conservative.

That being said I easily exceeded all the mins and didn't need to claim other types of PIC allowed to get in the door.
