    Really good shooting! It would be interesting to know how rough
    weather observations and less than good horizon conditions compared to
    the average. That Timex Ironman of yours is way better than average
    and should be kept in the sextant box for CN only. Did you use the
    same sextant for all the shots and was index error constant throughout
    the trip?
