It has already been demonstrated that it is inferior in design,

It is not an antenna - it is a wire that demonstrates
traveling waves by eliminating reflections.

We turn on the transmitter, and look at the SWR due to currents
reported:
8:1 SWR at the transmitter end with the current phase swinging
like a pendulum. With something like 300 segments, that is
roughly a 18 degree shift per segment along the wire (Cecil's
forecast was 0)

Sorry, Richard, that is a false statement. With traveling wave
antennas, there is a phase shift per segment. An antenna with
an SWR of 8:1 is neither a traveling-wave nor a standing-wave
antenna but is a hybrid between the two. As usual, you have
either confused yourself or are trying to confuse others.
Sometimes it is hard to tell which.

A 1/2WL dipole is a standing-wave antenna with an SWR ~20:1
on the antenna wire. Take a look at its current phase.

A traveling-wave antenna needs an SWR close to ~1:1 to be
a good example. Whether by accident or on purpose, yours
is a very poor example.
