That's a good way to do it when the seas are rough and
the horizon hard to judge. We call that extrapolation.

Sorry Neal, I never used that method to take LAN ..... too hard to judge
the right moment .... if you're going to use this method, best to take a
sight 10+ minutes prior to LAN and note the time and sextant altitude,
the take LAN (no close time really needed) then a third sight and time
when the sun returns to the altitude of your first sight, and work time
for LAN from that.
