I would say the relation Lenght::SQRT(bang energy) is
more suitable for a single shot discharge test on a
given coil.IOW,in this case Lenght~Vout is a strong
depedence in a typical TC output potentials ballpark.


But these devices develop sparks by the virtue of
subsequent bangs owing to remanent channel ionisation
and,to some extent,space charge debris.
Hence the complications.
For a fixed power input on a tested coil  ,the
relation may turn to be weakly correlated with
experiments in 120...240 BPS range,while being
reasonably well correlated in 500...1000 BPS range.
I guess some OLTC experimenters will be probing their
systems as regards these matters.
I think J.Freau did some tests on his spark gap coil
in the past , and made comparations between 120 BPS
and 240 BPS mode,so he may wish to comment more about
it.

Cheers,
Boris
