Granted, one spark per rev above 3500, BUT the primary voltage is still above
300 volts so
the secondary voltage is ALOT more ( not sure just how much) even in the single
fire mode.
The "window' closes above 3500 and there is only enough time for a single fire
but it is
alot hotter. This is the way I interpit it, OR ... IMHO :-)
