I would also prefer that the figures were given as a ratio as that is the way they are represented on published gradient profiles, (perhaps could be achieved by the reciprocal of the %age gradient).

That rather depends on the country of origin. Here in continental Europe, all gradients are, and always have been, expressed as percentage (or permillige, if that is the correct word - expressed as 0/00, so 1 0/00 is 0.001).
So the best way out would be a user option for the required format.
