Coax short

I know that a coax open is imperfect since there is fringing capacitance. Is a coax short perfect? Presumably, it has some inductance due to current flow at the short (metal disc) between the outer and the inner. The larger the cable diameter, then the further the current has to flow to get from the inner to the outer, so the greater the inductance.

As far as I can tell, however, this is not taken into account in a cal kit, so how is the time taken for the current to flow from the inner to the outer accounted for?
