I did a little thinking.
Since (from you) Cself = 0.256479 * H + 0.78646 * D. If you
set H = 0.78646 and D = 0.256479 you will get the largest coil
(as in most wire which leads to more inductance) for a given
amount of capacitance. It just so happens that H / D or
0.78646 / 0.256479 = 3.06637. So this would suggest a
reason to use a height to diameter ratio of 3. Hmm
Just a thought.
