Duane,
I remember seeing your nice phasing project on Richard Hull's videotape.
Is it possible that when the coils were 120 degrees out of phase so that
all the sparks connected at the middle, that this large ionized sparking
area behaved like a giant toroid or topload, and lowered the resonant
frequency due to this extra capacitance of the ion cloud in this mode?
When the coils ran at the same frequency, each coil would "see" only
its own (smaller) ionized spark cloud.
Cheers,
