Occasional hits, but at least 10 in a one minute period.

I don't see a difference in the two, at least for the purposes of this msmt.
If the grounded terminal is placed at distance X, then the coil system
under test must possess a "free air" capability of X in order to produce a
steady, connected arc of X length.
