Hi Greg -

 I would be interested in your results when they are available. 
 Several years ago I went thru this process and published a graph in the
Tesla Coil Design Manual. The graph was made from data I had collected from
over three dozen coils built by myself and other coilers. The data was
converted by math regression into equations that could be made into graphs
and used by a computer.

I ran into difficulties because I found that coilers were using many
different methods to measure spark length and power. There were no
standards. I showed a drawing in the TCDM to standardize the spark length
measurement. However, the power measurement was a problem. As you know the
true power is confused by volt amps, watts, RMS, Instantaneous, power
factor, etc. Coilers have never agreed on standards for this parameter.

Let me know if I can be of help.
