...to account for different current flow at the skin versus the center.

Ampere's Law tells us that current through a wire is confined to the "skin".

    Ok, then you need to decide whether you will do your computations from the skin surface, or assume the current is at the center of the conductor. A skin calculation will be quite abit more difficult. To be honest, the whole idea of trying to accurately compute these things from formulas, for the real world is mind-boggling, if not futile.

    I'll bet they use some sort of supercomputer simulation, to get formulas with fudge factor constants for different conditions and materials.
