From the Honourable Damir:
If I understand you correctly, with self resonance f~1kHz and L~650H, we can expect:

Cw = 1 / (4Pi^2 * f^2 * L) ~ 39 pF

Can you explain your results / findings in more details?

*********************

It's too bad that half the windings don't have a quarter of the capacitance!

Half the coil has half the L, unless it's by itself...then ov course it has a quarter of the end to end L.
cheers,
Douglas
