To me it seems that the "best" clock should be the one with the least average deviation from day to day. I don't understand why consistent deviation is best, because clocks that increase even in consistent amounts become inaccurate faster than clocks that increase/decrease inconsistently but to a lesser degree on a day-to-day basis. I was just hoping you might be able to clarify.
