    Thanks again for all the links.
    
    I've worked out how it is possible to use a simple table to calculate
    azimuth.
    
    My confusion came about because I read that the "assumed position" was
    an arbitrary position, however given that a 3 significant digit cosine
    take one page in a log table, then for an arbitrary two angle sum, one
    is talking about hundreds of pages for a 4 significant figure double
    angle table.
    
    From what I understand so far, the assumed position isn't arbitrary,
    but is a whole number of degrees away from the geographic position,
    making the tables much much smaller (by some 3600x)
    
    To be in simply, I was misled into believing the assumed position was
    something to do with the desired outcome, rather than a simplification
    of the calculation!
