The mutual inductance can be calculated by several methods (I will
implement one in my program when time allows), and is also easily
measured in an experimental setup. It is not a very critical
parameter, unless you are seeking the absolute optimum of one
of that particular values that result in maximum energy transfer.

Skeldon et al compare the idealized solution with the actual
waveforms of their coil. A point that may use empirical data is
in the determination of the equivalent resistances to add to the
primary and secondary circuits. The equivalent resistance of the
primary spark gap is difficult to model accurately, and the
effects of dielectric losses, skin effect, proximity effect, and
irradiation in the secondary coil are also not so simple to model
without experimental/empirical data.

This I would like to see too. I have tested it only with a coil
operating at low power, and in that case the results match very
well.
