Cheers & thanks for a great answer, Steven .. very clear ..

The conventionality in this case groups matter/antimatter into symmetrical pairings.
For example.
Protons/Antiprotons:- (1) and (2)
Neutons/Antineutrons:- (2)
Neutrinos/Antineutrinos:- (4)
For (3) If matter has +1 (or -1) parity then the corresponding antimatter has -1 (or +1) parity.
