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?

===================================
Roy,

What do you mean by end-to-end C.

What most people would call "self capacitance" -- the equivalent
capacitance from one terminal to the other.

But very recently you did say "Reg is right" when I said "All coils
behave like transmission lines."

More specifically, you said:

EVERYTHING has Inductance, Capacitance and Resistance, and therefore
behaves as a transmission line.

I agreed with that. This doesn't mean that I agree that you can choose
any C you like from any point to any other, plug it into a transmission
line formula, and get a meaningful result. Transmission lines are two
port, four terminal devices, so a completely isolated inductor or other
component, by itself, can't behave as a transmission line, except by
assuming some C to the Earth.

You and I agree on most fundamental matters.

I'll have to take your word for that. It isn't always apparent by what
you say in your postings.
