Coupling vs secondary voltage chart

Hi All,

I set ScanTesla to find out how coupling affects top voltage.

I used the data from my big coil:

The coupling ran from 0.01 to 0.99 in 0.001 steps.  The load was 3.83pF 
calculated from the initial primary cap energy (21kV  28nF) using the Freau 
formula.

The primary coil was tuned to maximum top voltage at each coupling level to 
within 0.1uH.  I cut the fluff out of a special optimized version of the 
program so it could do 1000+ models/second!  441000 calculations (400 
seconds - 1,200,000,000,000 machine cycles!) later...  Here is the graph:
