I am not sure (yet?) that a star pair optimal for St.Hilair intercept method (i.e. the one suggested by vol.I H.O.249) is also optimal for the direct position computation. Looking at the picture (attached, courtesy John Karl) I'm inclined to believe that a star pair optimal for the direct position computation should represent a triangle (star1-Pole-star2) such that observer occurs in the very middle of that triangle. Whether this condition coincides with a near-90° difference of the stars' azimuths - I do not know. That's why I ask the initial question.
