With your averaged error of "Difference |0.36'| " and going by the old adage
"a mile is a minute" that means your eyeball error will put you off by about 1/2
mile. All things considered, that's a zero error when a sextant position at sea
from a small craft may only be accurate within 2-5 miles in the first place.
Just mark your position with a slightly thicker pencil.<G>
