    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.
