No these measurements would be meaningless statistics, since putting the pygmy or the Fon in the same “race” as the Masai or the Peul is a very stupid and silly thing to do, like making a comparison of hte average weight of Americans to French and making some conclusions about the genetics of Americans and French as an average. A silly, stupid and non-scientific engagement.
I think the question is why you never accept the way you see these things is superficial and ignorantly organised. They have presented to you the scientific reasons why and explained, but you pretend never to have seen any argument. No, you make arguments based on some strange fantasy. I would not blame them for making conclusions as to why.
