It is a little of both.  Most were done with math and applied physics 
techniques, and a lot of testing was done to determine best performance. 
The trade off is total coil resistance, surge impedance of each setup, and 
total inductance.  We did a lot of testing and used JAVATC to fine hone the 
results.

I always found the best performance is definitely related to the radius of 
the sec coil.  John Freau confimed this in one of his experiments in which 
he coaxed a 43 inch long spark out of a 30 mA NST.  He used a huge sec dia.
