Should be some basic geometry if you know the distance between the upper and lower balljoints, and the current angle.

Assuming 9" between ball joints and a currently vertical spindle,

3.14 * (4.5^2) = 64 (radius of a circle)

360 * (64 * .25) = 1.4 degrees (360 degrees in a circle times the fraction of the circle that is 1/4")

So 1" should net about 5.6*, 3/4" would be around 4.2* gain
