Yes that is the case as far as practical accuracy is
concerned. Theoretically, accuracy is improved with
shorter intercepts because the LOP, which is treated
as a great circle for practical navigation, is really
a "small circle" which would cause increasingly large
errors with very long intercepts. But in the real
world, choosung an Alon within 1� of your location
shouldn't result in any perceptable differenc. I know
some purists might point to some extreme cases such as
in polar navigation or very high altitude sights but
the above is the generally true situation.
