I find the article and paper somewhat frustrating. It doesn't say anything new about da Vinci, and it sure doesn't seem to add anything which isn't already an accepted idea in biomechanics. The article revives vascular constraints as a strawman before beating it down again, as if it's still a theory of limb structure thats taken seriously. My takeaway: da Vinci's rule is easily explained by modern foundational biomechanics.
