In case that sounds like nonsense, the second ringup presented the
air with a higher voltage further out in time but at the expense of
presenting a null in between as energy ended up back in the primary.
In effect what happened was (air streamers only):
*
*
* *
*
*
* * 1st notch quench
*
*
* *
* *
*
* * * 2nd notch quench
1st ringup time and amplitudes are identical. I have the two
waveforms in the scope and am looking at them superimposed right now.
