I don't think describing others as "losers" comes across too
obviously as a joke. Never mind.

I think most if not all here recognized it straight away. A shocking
(npi) error to make by people who are supposed to be experts.

Maybe not. Consider that at the point of spark initiation the
terminal is at some high voltage - for a brief interval it could be
considered to be HVDC. Spark propagation is a pretty rapid event by
comparison with the resonant frequency. I think you can discount the
impedance of the secondary when considering such an event.
