Weedonhill Wander - Bonus Cache Mystery Cache

A final cache, full of swappables, to finish up what's hopefully been a lovely walk.

This cache is not at the listed coordinates: you will need to obtain letters and their corresponding values from other caches in the Weedonhill Wander series.

The cache can be found at the following coordinates. You don't need to leave the path to find it, and you definitely don't need to go into the nettles.
N 51 40.[B+H-C][G-E-D][HxJ+H]
W 000 37.[ExA-A][I+F-C][CxExJ]

If you have difficulty finding some of the caches in the series, you can still potentially find this cache by using the following information:

• Each of the letters A to J match with a different value from 0 to 9.
• A+B+C+D+E = 22
• F+G+H+I+J = 23

Well done GoldenRanger for a remarkably serendipitous FTF.
