    When rating my two regulator clocks I work the other way around,
    starting my stop watch on the minute by WWV on 10 or 15 MHz and
    stopping it when the clock beats the minute. The difference is the
    error. Hence it is easy to obtain a rate, no doubt dependent on
    variations in my reaction time.
