Thoughts on spark length and the "Freau Equation"

I would assume that the equation proposed by John Freau for predicting max
spark length  (=1.7 *sqrt(VA)) is based on 120 pulses per second.  That is,
it's really more of  (length in inches)= 1.7 * sqrt(120 * energy per bang) =
18.6*sqrt(energy per bang in Joules).

Obviously, there are breakrate effects on spark length, but, for rates in
the 100-200 bps range....
