Doug- I wonder, if perhaps dividing the number of sites into 360 degrees and spreading them out evenly is counterproductive? Consider that case of 8 sights. If I plot them evenly about I'll get one smudge on the chart. But if I plot two sights each at 4 positions...The difference between the two lines from any one direction will also tell me that I have an error of at least that amount. Wouldn't that information be just as useful? Aside from star sights at night on a cloudless sea, who would have the luxury to take 8 sightings in equidistant directions anyway?
