Rob and John,
	I would suggest that this "sweet" break rate is at the
resonant frequency of current limiting ballast inductor and the TC's
primary cap.  At this frequency, both the output I and V go to Q times
the normal I and V! Remember, this IS a resonant system on BOTH sides
of the spark gap.  I'd be interested in seeing if the math proves this
