OK I know what you mean.  I've tried 2 gaps, 4 gaps, 8 gaps, and
12 gaps in series, so all the gaps fire each time the rotory fires.
A series rotary.  I never saw any difference in spark length in any
case, so now I just use the normal 2 gaps.  Using more gaps,
the quenching is a little better, but the losses are a little higher,
so it's a tradeoff which is probably why I didn't see any difference.

Using an external gap may also help the quenching, but again,
the losses may be increased.  But there is much controversy in
all this.  Some folks have found much higher losses using 
the multiple gaps (either external static or built in series rotary),
whereas others have found the losses to remain about the same,
so it may depend somewhat on the coil parameters.  It seems
like not much work has really been done in this area to really
tell the complete story.
