Hi Malcolm,

	It comes from measureing my coils.  My large coil delivers about 225 watts
to the arc and burns 276 in the gap.  My small coil delivers 80 watts to
the arc and burns 112 in the gap.  So I generalized...  My gaps do not try
to quench anymore but I try and minimze primary loss.

Cheers,

	Terry
