Hi Terry,
          This is a very interesting observation indeed:

I actually noted in more recent notes on my artificial line 
model (which I didn't release to the list) that Cdistr appeared to 
follow the electric field intensities along the resonator.

    The other night, I was leafing through the CSn yet again and 
found a section somewhere around p220 where Tesla actually noted that 
he thought Cself of a cylinder could be used as an approximation for 
his Cdistr. I hadn't previously seen that note. 
    I think you are absolutely right that Cself has little to do with 
inter-turn capacitance. Tesla never realized this at first and made 
heroic attempts to cancel inter-turn capacitance. 

Very nice experiments.
