    I use the inverse of your method, I start counting seconds from the
    time of the sight until I can look at my watch, never more than 3
    seconds so less opportunity for the count to get off by any
    significant amount. I use a digital watch that has a push button for
    illumination at night. I check its error after the round of sights
    using a more accurate watch or radio time signal.
