[SI-LIST] Five Wire Formula in Wadell

Does anybody have experience with the five-wire impedance formula
in Wadell's "Transmission Line Design Handbook" (section 3.3.4, page 70)?

The five-wire problem refers to a center signal wire surrounded by four
ground wires at constant distance.

I have a "feeling" that the impedance comes out too high ...

BTW, I checked the errata sheet but couldn't find any changes to this 
formula.

Any other reference or a well-known example might help too.

Thanks!
