Also, electrolytics had/have very wide tolerances, so it was more economical in mass production of radios and TVs to specify the minimum value needed and let the cap maker cut the materials down to an amount that would guarantee that minimum. So, the stamped values were determined by a manufacturer's mass order, not by pulling from standard-value bins. Especially true for multi-section caps of course.
