John is quite correct on this matter.

If you want to determine a "true" spark length for you coil, rectify the AC
to DC and then insert a large value resistor (say 20 Meg) in series with the
HV power supply to the cap.  This will "fire" the circuit once every 2-3
seconds.

You measure this output spark length and you will have a close to true value
for the output of your system.  This prevents "spark growth" as a function
of power input.

This is a HF AC current however the spark length is very close to what a DC
peak value would be and is accurate to determine actual output voltage.
This also is in very close agreement with Terry Fritz's antenna pickup
voltages.
