Steve,
In your plot how are you defining S, the spacing between conductors?  Is it center 
to center?  Is it consistent for both the approximated and actual curves?  It 
appears that only the actual curve uses the center to center definition; in the 
limit as S-->d  the inner edge to inner edge spacing goes to zero, and Zo also 
goes to zero.
