RE: bps and spark growth, was Superior Power Supply

I consider your experiments important. I would like to see you use the input
wattage for your tests so you can average out the spark output. The problem
with the bang size is that it may vary with the random spark length.

Boris,

The bang size was kept constant at every bps.  So the power
input was much lower at the low bps.  It is likely that the bang
size was too small to give best results at a low bps.  This is
why I said it depends on the system.  A coil with a small
bang size will need a higher bps to give long sparks and draw
in more power.  Greg said that the larger topload helped a
little to give better coalesce at the lower break rates, but not
really much difference.  I assume you're refering to Greg's
old coil (not the Electrum).

Yes, as you say, a low bps and large bang size gives the
best efficiency.
