Re: 20 joules at 100 bps vs 4 joules at 500 bps - any difference?

To all,

I believe two things combine to produce long sparks (in this context). 
First is streamer growth from a single bang and a larger bang energy 
produces a longer single bang streamer. Second is growth building from 
previous bangs resulting from appropriate BPS.  As bang energy goes up the 
first mechanism seems to be favored.  As BPS goes up, the second mechanism 
seems to be favored.   Since the power to the coil system is bang energy * 
BPS and many of us want to get the longest spark from a given power source, 
it would seem like a good experiment to keep the power constant and vary 
the different combinations to find the optimum point where decreases in 
bang energy from higher BPS is not compensated for by improvements in bang 
to bang steamer growth.  Has this experiment been performed???
