Well, unless they aren't making conductors like they used to, I'd say the
worst case internal resistance of a hi-V capacitor is on the order of
1/10's of an ohm -- insignificant when compared to the 220,000 ohms of
the "target".

Do not confuse the dielectric resistance (which is hopefully very high) with
the plate/conductor resistance, which can be arbitrarily low.
