BUT, once the fire is off and going, what real benefit is there?.  On some
applications, if the chamber is so turbulent that it keeps "blowing out" the
initial flame front then fine it's need, but that makes me wonder about the
design logic of the chamber porting if it's that even close to being a well
executed design.

Now we're into the promised land.  Reading the ionization items.  If you
read (sorry I've lost the number) the Jacobs Patent he specifically mentions
that as part of the SCR (?) turn off strategy, and that seems to make sense
to me as far as if there any reserve of energy that is still usable, rather
then starting the recharge cycle reguardless of what the spark is doing.

Makes me wonder thou, what difference is there really, other then moving
where the cap is?.  Also, then is the guestion if you turn the primary off
really "hard" and fast (possibly with some reverse voltage) and use a coil
per plug what could be better?.  OK, other then lab stuff (ie micrwave), or
never never land stuff
