Re: 20 joules at 100 bps vs 4 joules at 500 bps

No wonder my larger DRSSTC has a Freau number greater than 2
(confirmed 3300W input for 120" sparks).  And interestingly, it seems
that my sparks would grow from say 3 feet at 450VDC to like 9 feet a
500VDC... there was a very sharp point at which the sparks just took
off (no pun intended).
