Good point.
High current spikes in short time intervals due to
parasitic L-C elements (top turns of the secondary
,toroid ,discharge path etc) are attainable in such
experiment.
As Bill said,high frequency modes of the secondary
might be excited over secondary to an extent as well.
Enhancing the release of the energy that way.

But I also suspect that most of the energy is released
in low frequency mode at frequency determined by C
value of the storage capacitor and L (DC inductance)
of the secondary.
It would be interesting to make small scale experiment
and appropriate msms to see what would be going on...
To use say 7 joules instead of 7 kJ.

All the Best,
Boris
