Hi Ed,

Yes,  there are short term variations on the BPS,  one half cycle may 
have no firings and the next could have three, for example.  It does 
average out for the most part.  I'll have to redo the simulations to 
see if there are patterns that develope with certain 
combinations.  At the time, I was only interested in the average BPS 
of say a 4 second simulation time.  The BPS variation was very short 
term (less than 100ms) from what I remember seeing.

   Try setting the peak voltage near the breakdown voltage of the 
gap and playing with the capacitance.  You can get conditions where a 
spark only occurs after several cycles elapse, a condition I've seen 
with a "real coil".  The real coil has variable leakage reactance 
which I don't know how to simulate.  Something else I've seen in a 
simulation which I think is impossible is the sparks occurring on 
only on one half of the cycles, a condition which would result in DC 
flowing in the transformer.
