There is a difference (as discussed long ago) in NZ Law; there,
every flight-test/renewal is logged as PinC with the ATO logging co-pilot -unless you fail the flight-test/renewal, in which case the candidate logs dual and the ATO PinC.
The assumption there is that, as you are being assessed for competency to act in that role, you must be assumed to be PinC. Unless you fail.
