If an inductor by itself delayed phase as much as Cecil claims, we

There is another explanation.
A lumped circuit has only one resonance. A transmission line has an
infinite number. It certainly isn't necessary to impose a strict test
of this. Finding second, third, and fourth harmonics for an inductor,
in situ, would certainly be compelling evidence of transmission line
behavior. Otherwise, any delay obtained through pencil whipping the
various formulas (and Reggie's equations veer far from the references
offered) is strictly what occurs AT RESONANCE, and any interpolation
of that delay to other frequencies is a presumption not yet proven.
