We hesitated for months before doing this cache - would our maths skills be sufficient? Finally we decided to take a helping brain with us and thus found the cache without any further problems.
Two hints to the cache owner: the tree at position A is broken and probably doomed to be cut down. The letters at position C are hardly readable (we didn't have the right pen with us to renew them).
Nice walk in a beautiful area formerly unknown to us.
