Carry adjusted lats, deps, and dists to 0.001', directions to 0.1" to minimize rounding errors.

Problem (1)

      Unadjusted
Line Direction Length (ft) Latitude Departure
101-102 S36°00'00"E 379.25 -306.820 +222.918
102-103 S75°23'18"W 408.90 -103.152 -395.675
103-104 N14°43'29"W 298.65 +288.842 -75.909
104-101 N63°59'20"E 276.55 +121.280 +248.538
