The literature disagrees with you. So does NEC. See the IEEE Emerald 
Book and Green Book. Also see Ott. 

The conduit DOES greatly increase the inductance of a wire within it 
that is NOT connected to the conduit at both ends. But when you 
connect the wire on both ends, you make the conduit part of the 
circuit, and the current flows on its skin, just like it would on 
any other conductor.
