The point I’m making is that if you put yourself in the shoes of your character, and if the only knowledge your character has of halforcs is their adventuring companions (metagame concept: PCs) then the impact of the +2 Str is insufficient to lead to the conclusion that halforcs are strong. The sample size is too small, and other factors (specifically attribute assignment) have a greater impact. You would have to adventure with dozens of other PCs, at least several of which would have to halforcs, before it would become apparent that halforcs are stronger than average
