I can further manipulate the numeric values so as to place the blue at 0 like this.

The cloud output, numerically, is TheRange(1/3 to 1).

Using a math node I have established a manipulation of the Clouds like this:

Clouds * 1.5 - .5.

Substituting the range of values, I can conclude that the output of the Math_Functions node is:

TheRange(1/3 to 1) * 1.5 - .5

= TheRange(1.5/3 to 1.5) - .5

= TheRange(.5 to 1.5) - .5

= TheRange(0 to 1)

Yay! I converted the original range to my target range 0 to 1. Boom - the middle sheet stretches from 0 to 6 inches exactly now.

All of the manipulations along the Displacement chain of nodes has NOTHING to do with the Diffuse_Color chain. They are unrelated even though they eventually both consume data from the Clouds node.
