Doug, I'm sorry if I misunderstood, but it looked as if you
computed the time of LAN at your estimated position, then
took a single sight at that computed time (to the best of
your ability). While this might provide a reasonable estimate
of your latitude, using it for longitude involves a circular
argument -- the only input is the time you computed, so of
course your result is equal to your estimated longitude.
Or was there some other procedure used to determine the "time"
to record along with the sextant altitude?
