No ... it is a black box because I don't know the algorithm it uses, nor do I know how this algorithm was derived. All I know is that I plug in values and it spits out values - this is what we call a "black box". I'm not saying they are necessarily wrong, I just don't know how they work.
Please elaborate on "good physics". A Gaussian distribution is merely a statistical argument and is not "good physics". Good physics starts with first principles.

p.s. Thanks everyone for the advice. Still "mulling" things over in my head...

Use JAVATC. It's not black box, but based on solid equations based on good
physics (Gaussian distributions, etc.)
Enter the data required in the transformer section and it will provide your
exact xmfr impedances. It will also give you a good cap value and pri turns
value.
With this size xmfr either a .06 uF 80 kV or 0.1 uF 80 kV cap will work very
well. For most medium size coils driven by pole xmfr, with spark output in
the 6-8 ft range, I would go with the .06 uF size cap. For coils running
10-15 kVA, with spark output in the 10-15 ft range, the 0.1 uF size will
work best.
Be sure to use a large coil dia, in the 16" to 20" range for optimum
performance from a pole xmfr powered coil.
