BT?
If you log any P1 time at all, you have to agree beforehand with the other pilot how you'll split the time. If indeed the LH seat man (or club rules if it's one of theirs) will allow this. If you fly behind a VP or constant speed prop as P1 you have to have relevant differences training signed off in your log-book.
No P2 in little aeroplanes as said.
So it sounds as if you were "speaking ballast" and nothing more. Contrary to advice you have to log what you're entitled to, not what you think it may have been!
