Ah. I overestimated the intelligence of my fellow man once again. This is my bad.
Not only that, it's soft connective tissue that causes this aesthetic, meaning there's high genetic variance (the reason some people have lopsided '6 pack', or why some have an '8 pack'), & high variance based on sedentary vs active, diet, etc
