John,
On August 15, 2009, I posted a reply on a thread entitled "standard deviation", regarding accuracy of celestial
navigation. You might find this of some interest.

One Navlist discussion on the accuracy of sextant sights at sea happened back in September 2010.
A pdf document of a study on this topic was attached to George Huxtable's post g14011. The average observational error, by experienced professionals on the relatively stable platform of a big ship's bridge was thought to be around 0.7' of arc.
