Bert, All,

Bert has given this a lot of thought, too!  He is correct so far as I can
see on all his points.  Which blows back to my original point.
Theoretical discussions regarding the ultimate limiting voltages are good
and valid, but can't really tell us what the real output voltage from a
given coil system will be!   EVER!   Mainy things are theoretically
possible.  Everything can be scientifically analyized "ad nauseum" with
mathematics and philosophical semantics.  Few of them are realizable or
even doable out on the firing line!

Regardless of what we think the terminal capacitance really does (
more voltage, more current, more energy) it gives LONGER SPARKS from any
given system provided enough energy is pumped in to break out.  That's
what most of us build coils for.
