Incidentally, parabolic means either "resembling or expressed by parables" or "having the form of a parabola", so I don't know exactly how it relates to ramping in any area besides marketing. A parabola being a "Plane curve formed by the intersection of a right circular cone and a plane parallel to an element of the cone or by the locus of points equidistant from a fixed line and a fixed point not on the line" and a parable being "A simple story illustrating a moral or religious lesson"
