All this talk about the theory is well and good, but in actual practice, what
ever works does!
Had an engineer at Collins Radio tell us (in the 60's) that "... the SWR will
circulate until
it is dissipated." He just didn't say where. Could be in the tank circuit or
the antenna.
Had another engineer that had a favorite saying "If the facts do not conform to
theory, they
must be changed."
Hope to interject a little levity into the hard core discussion of the theory.

The "antenna analyzer" of the MFJ 2xx series, tells you a total impedance, ie
it does not break it down into capacitive reactance or inductive reactance
impedance terms, unless you use the advanced operating tips.
Changing the frequency of measurement shows if the impedance is mostly
inductive as it will increase at a slightly higher frequency away from
resonance. EG Xl equals 2 PifL, higher frequency, higher reactance.
