Why do you suppose a little bit of dielectric on the wire would make a huge
change, when the majority of dielectric is still air?

So, these numbers are for BARE copper, right?
Using insulated wire changes things a bunch....
For instance 18 GA THHN/THWN has an approx. dc of 2.35, XLPE has a dc of
5 or so.... As the dielectric constant gets larger, things get real....
fast.
18 GA THHN/THWN... (dc = 2.35 approx.)
To get the same 464 Ohms, the Center to center distance must increase to
7.52 inches or so...
