Aaaarrgghh! Work with me here PGA!
You say you did an integrated course, just like I did. That means to get your CPL you had 100 hours PIC, made up of your 50 hours PIC and 50 hours SPIC. You have had 100 hours PIC since the day you finished your flying training! Add you 150+ hours PICUS as a co-pilot and you're ready to go! Just make sure you get those night hours
LF - It was explained to me as :
SPIC - Student Pilot in Command i.e. flying a single pilot a/c such as a Seneca as P1 but with an instructor on board at all times.
PICUS -(or P1/US) - Pilot in Command under supervision i.e. Multi-crew aircraft and flying as P1 when you are not the captain. You are not P1 as you are not the Commander but it is your sector, hence you log P1 and remark PICUS in the remarks column.
