It's best to actually measure the potential.

Rectify the HV to DC, and then use a 20 Meg HV resistor in series with the
output to the cap.  This will fire a single pulse at peak DC kV on the cap.
You can measure the discharge between the toroid and a suitable ground
electrode.  This will provide the peak potential of the system.

You can correlate this with a simple inductance ratio calculation --- they
should be in close agreement.  Most multimeters allow inductance measurement
of both pri and sec coils.
