One may notice from that code quote on big conductors that a 50% increase in size brings only a 15% increase in conductivity. Is this the flow of electrons on the perimeter of the cable factor?

Skin effect has some factor. Basic rule of thumb. Copper is good for 1,000 amperes per 1" square cross section. Aluminum is 700 amperes per 1" cross section.
