Say the average male is roughly 5'10" in the United States. Say there was a poll stating the ideal height for female is 6'2".. There would be less resistance to that than to this by far.
Say the average female cup size is 'B' but a poll said guys like 'C'' and D' cups. Nobody would be stating that the poll is BS just because it doesn't mesh with the average. People like things to be better than average.
That's because those are realistic. The amount of guys that are 6'2" is going to be close to guys that are about 7x5.5, not 8x6.5. If this chart swapped height or cup size rather than penis size, it would have ideal height at like 6'8"-7'0" and cup size as like DD-E (I think E is a real size?)
