Hi Mike,
	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.
