concurring in part and dissenting in part. I agree with the majority’s resolution of the second and third issues. However, with respect to the first issue, the denial of appellant’s post-test-year wage adjustment, I dissent on the basis of my dissenting opinions in Consumers’ Counsel v. Pub. Util. Comm. (1981), 67 Ohio St. 2d 372, 376 [21 O.O.3d 234], and Ohio Water Service Co. v. Pub. Util. Comm. (1983), 3 Ohio St. 3d 1, 4.
