Adam,

I don't think you should call the result of the D = 25 + 40*Vbar equation
the Neutral Point.

It is supposed to be an estimate of a target CG with something like 15% static margin. I haven't checked the formulas, but if you move forward 15% of the MAC on the top drawing you're pretty close to the suggested CG from the Tail Volume Coefficent Equation.
