Your shunt looks exactly like mine. There probably is some skin
effect but I'd not think that would be inductive, so it would merely
cause an apparent increase in the indicated current. That the shape
of the wave in my "5" image is essentially the same as that in the
5A simulation image seems indicative to me that it is reasonably
acurate. (And in that 5A image, I rather wish I'd thought to change
the scale of one of the curves so that they did not overlap.)
