Gerry,

If, as you suggest, "As one moves up the coil, the displacement 
current off of each turn increases (due to increased AC voltage) and 
reduces the conduction current in the wire." where does this 
displacwment current flow to and from off of each turn?

Perhaps it's best to analyze with instantaneous power.  Basically, 
instantaneous high base current times low base voltage equals low top 
current times high top voltage.  Maybe there is just low top current 
and no real displacement current in the upper coil windings.  Maybe 
in a non sparking coil what people call "displacement current" 
actually radiates out into the air dielectric from the top load.

Once a spark forms there is a plasma conduction channel and this 
"displacment current" suddenly turn back into ordinary conduction current.
