any time you're in the aircraft yourself or the sole manipulator of the controls then you'll log the time P1
Port Strobe, that is wrong.
Any time you are Captain, you log P1.
You can be Captain but not at the controls (e.g. a flying instructor whose student is at the controls, or a B747 captain when the co-pilot is the pilot-flying). You can also be at the controls, but not be Captain (e.g. most of your training, when your instructor was Captain and logged P1).
