That is particularly interesting because the result shows a deviation
from a simple power dependence. Now the dependency becomes voltage
and/or charge availability,...... perhaps..... because we don't
really know what part the oscillations might play in spark
initiation, propagation with repetition and continuance. i.e. the
oscillations occurring before the secondary is drained by the output
discharge are continuously altering the instantaneous charge
availability at the terminal.
