    I am at the point that I can whip out Hc and Zn in 3-4 minutes on my TI-30XA
    (3 memories) with no paper or pencil needed from any AP I wish.  I am glad
    that I learned a tabular method first as it gave me a better understanding
    of what was going on, and provides me with a backup to calculator methods.
    
    I do agree I prefer a short intercept. Regarding long intercepts and
    accuracy, the offset table can to help nudge a point on a an LOP a long
    distance from the intercept to better approximate the COP.
