I've looked at the efficiency both from the point of view of the input
power and from the charge on the cap.  This way, I was able to
apportion the efficiency contribution of the charging circut, and of the spark
growth characteristics.  By using equal "cap-watts" (joules x bps)
for both 120 and 240 bps, I still found 120 bps to produce longer
sparks than 240 bps.  If I remember correctly, most of the 
efficiency resulted from the spark growth characteristics at 120
bps, rather than from the losses or other effects in the charging circuit.
