Please note that nobody has made valid measurements of the delay

=======================================
Dear Antagonists,

Why go to the great hazardous trouble of measuring it when it can
easily be calculated from physical dimensions of the coil.

Velocity V = 1 / Sqrt( L * C ) metres per second

where L and C are henrys and farads per metre.

Therefore Seconds Delay = Coil Length in metres / Velocity.

OK, I admit it's an approximation because coil turns couple one part
of the 'line' to another a short distance away. It is not unconnected
with proximity effect. This does not occur in a normal transmission
line. But the approximation holds.

See and amuse yourselves with program TRANCOIL.

It's hard to tell from this, but are you still claiming that the
end-to-end C of an inductor is the C of an equivalent transmission line?
Or even an approximation? Does your program assume this?
