Gerry,

Terry, myself, and others have done tests of this sort.  Using
NST's it's sometimes not desireable to fire at the peak capacitor
charge, because timing issues outweigh as a factor of importance
for longest sparks.  In such cases, the cap charges to a peak
voltage, then the voltage drops some before the SRSG fires.  If
one attempts to fire at the peak, the firing voltage actually will be
lower in some cases.  Each NST and cap combo behaves a little
differently.

The capacitor takes time to charge, so there's a delay between
the input voltage peaks and the actual firing voltage peaks.  The
amount of delay needed for the gap firing for longest sparks, also
depends on the NST and cap combo.
