Interesting physical as well as philosophical discussion about "inaccurate" dials.
One possible bottom line is simply what did humans want from a time piece. It seems a mass dial or any other "inaccurate" device must have met their needs and thus was for them a valuable item. Religious meetings, civic activities, and so on would be served well. If "inaccurate" dials get together those who needed to congregate, at the same "inaccurate" time, then is not the objective achieved.
