Very interesting results! It's amazing that such a complex distributed
circuit can be described so simply, but then again E=MC2 explains a great
many things as well! I like how this model explains a coil's tolerance
for shorted turns at the top, but do you think that most of the phase shift
in a standard TC occurs that close to the bottom (due to coupling?)

Do you plan to experiment with different tapers as well?

Indeed! I was curious if you have measured the voltage at all the nodes
along your new tapered line, to see how the _energy_ is distributed
amongst all the capacitors.
Good Work!
