Well I think it's agreed that spark follows at least a square if not 
cubic dissipation law so I don't know about linearizing the result 
like that. But I do think it's worth noting that things can be 
achieved with good supply-to-coil matching. Although I didn't set out 
to do this (this is actually a system I am building for someone) it 
is most interesting to see what can be done if power is used in a 
reasonably efficient manner. I posted earlier on some of the power
reaching the primary vs power drawn at the wall in the coil charting 
exercise. There is a heck of a lot of work to be done in that area I 
think and I think John Freau's results also support that contention.
    One of the best things to pop out of this is that I now have a 
firm guideline on how to match the coils I am charting to the results 
they are achieving and suggest where improvements might be made. That 
can only be of benefit to everybody :)
