I really think you need to be making these points to both Graculus directly and to Groundspeak. You may use my photographs and my coordinates (which I did supply to Lindinis). These comments on Facebook, GAGB and Groundspeak forums will probably attract much support.
The amazing thing is that the MoD have now documented that they have no control over Merrivale or Okehampton, but still Graculus won’t budge. It has to be taken over his head. All the reviewers seem to be “jobsworths” who can see nothing objectively.
