How many stripes does the relief captain have? 4? What's his title? Relief captain?
But sure, he's only called a captain; he's not a captain.

P1 is a new term to me. We use PIC time. And yes, one person on the flight deck logs PIC time. Because you can't log PIC time in the bunk. Or is that another euro thing? Logging P1 (if that's what you call it) time while unconscious in the bunks?
You are definitely not familiar with the FARs. In accordance with FAR 61.51, a relief captain will log PIC time when he is on duty and in charge on the flight deck.

It sounds like you're just making stuff up to justify your pretzel logic.
'A relief captain's not a captain' ... amusing. No wonder you were stuck working at Norwegian. Cream of the crop.
