One certainly has to be careful. But Dr. Corum's formulas
matched my measurements closer than I expected.

One thing is for sure. One cannot use the presuppositions
of the lumped-circuit model to prove the validity of the
lumped-circuit model and that is what has happened so
far. One also cannot use a signal with unchanging phase
to measure the phase shift through a wire or coil.
