Part 1 caused some head scratching about whether to include the air (brown) spot heights. However no decision was required since if you followed the instructions correctly the first five spot heights were black (ground) ones. Many missed the 51(1:50000) on the B1023 in the middle of Tiptree and most missed that the 54 on the B1032 was represented twice, in different locations, on the 1:25000(25) and 1:50000(50) maps. The correct sequence was 46(25) 51(50) 52(25) 54(25) 54(50). SH43 wasn't included - rule 19.

Part 2 was easier once you had solved the simple encryption A<>N B<>O C<>P D<>Q etc, a code which would have been familiar to geocachers which gave the clue "Now take the longest route remaining to the edge of the plotting area. The route check questions are the same as for part one." There was however a dilemma here. The truly longest route only contained four undisputable spot heights. The (off-route?) 58 at the staggered B road crossroads in Tiptree was included by some to complete the set. So I allowed Route 8: 71(25) 69(25) 67(50) 68(50) and 62(50), and Route 8A: 71(25) 69(25) 58(25)/68(50) 68(50)/67(50) and 67(50)/-. (Alternative display here) (Alternative PDF here)
