Hey I think it BS too, the resolution of these values that they gave me, they can't measure down that low.  They have it measured below 1 pico Henry (10^-12).  I looked up strait wire inductance on the net and it turns out that a 1/2 inch length of thin (0.005 inch) wire has about 10 nano henries (or 10,000 pico henries) of inductance.  Ohmite must have calculated the values they gave me.
