we too believe that the coding is an average for the 3 aspect head. In our submission we have to list indicative arrows etc (extra lamps) seperately to the RAG. Our submission is also complicatd as only one half of the county is under WPD. We were warned that WPD were going to audit installations and have been good boys and girls so far!
We also list sites that are metered, as they audit / check those as well.
