#potential ⇒ Object

a single % value based on the data in this point used as an input for another Base#plot call TODO: what is distribution of values of this function? we want something reasonably gaussian, i think.

w/o created_by_potential, rearranging the initial string in a series of figures alters the first 10 figures or so, and then they eventually converge back to being identical. (The ~11th figure shows no dependence on this initial change in ordering.)
