I love this subject. Do you think we can make a 2nd page on this thread?
The best thing to do is to sort it out with the intructor before you fly. if he wants the P1 hours then you don't have a choice unless you want the club currency to lap.
Some clubs will allow select memebers to perform currency checks, again sort it out with them before you fly.
As Bose says it does the odd hour here or there make a difference? I would suggest log it as PUT and make use of the time by asking the instructor to go though things you are not comfortable with or would not feel safe doing when solo.
