Bert,

I must mull this over a bit.  Your argument is compelling.  The coupling 
coefficient is inded the common flux lines of the two coils and the 
multiple feeds of the beats would be the resonant pumping of the 
secondary.  Regardless, if 85% of our flux lines were never common to 
both coils then 85% of the primary lines would never transfer energy.  I 
realize at resonance we are not talking simple transformation.  We are 
still talking energy linkage via magnetic coupling to another coil.  If 
that coil were moved farther away less coupling means grossly reduced 
energy transfer.

  In resonant systems this may or may not affect the voltage output at 
all!  When over couplied, with a given gap system, a reduction in 
coupling will actually increase spark length dramatically! (increase 
output voltage.)  The energy transferred has decreased severely, but the 
performance, or spark output, has increased dramatically.  The losses due 
to magnetic coupling in our air core systems far exceeds all the total 
losses of all the other agents combined.

I have had my doubts about the Corums and the 1/2 cycle theory for some 
time.  I hope to do the H2 thyratron testing soon and varying the dwell 
to a moderate powered system over a long range and see how it affects the 
spark to hopefully agree or disagree with the theoretical approaches.  
Naturally I hope to vary the coupling range of the systems independently 
at the same time.

Good post and more stuff to digest.
