Re: Racing Spark Prediction

That's correct. and ... that's why it isn't a "pure" waveform. It
undulates in a slightly erratic and non-linear fashion.
I'm thinking that the fundamental frequencies (the two that split
further apart when the coupling is increased) also can beat with
each other along with any overtone frequencies (per Paul's animation).

I think that the theory is that racing arcs are caused by a
reflection of a third harmonic bouncing back from the top of the
coil on the first cycle. Paul or Dmitry can confirm that. Having
the top third of the coil reverse wound is supposed to squash that
3rd harmonic reflection and perhaps cure the racing arc. At least
that is how I understand it.
