The Formula

What advantage would
knowing about any current "taper" give you?

The advantage of understanding reality. In the
following example:

Source------------A-//////////-B----------------
wire coil wire

The current at A is measured to be zero. The current
at B is measured to be one amp. Does it mean that
there is an unknown source of energy magically entering
the coil from the outside world? Of course not. It
just means that we are dealing with standing-wave
current and we cannot even tell which way its phasor
is rotating.

It just means that the forward traveling current and
reflected traveling current are of equal magnitude and
opposite phase at point A. They are not of opposite
phase at point B. The traveling wave phase shift through
the coil explains everything.

No need for any lumped circuit magic. No need for
a magic source of extra energy. A distributed
network analysis is all one needs.
