I wonder if Jim means "...of the last cycle...", not the first cycle.

Also, I can attest to the larger field when not "breaking out", that Jim
mentions:  With no spark, my s.s. coil lights up all the flourescent
lights, misc. neon tubes lying about, etc., in my workshop.  With a spark
there's very little of that.  A subjective measurement, but indicative.
