Welcome to OpenStreetMap and thank you for updating this part of Nettleden with Potten End BR 5.

I don't know if you would find it helpful, but there's a resource for checking the mapped status of public rights of way at https://osm.mathmos.net/prow/progress/herts/dacorum/nettleden-with-potten-end/

There are also some suggestions for tagging PRoWs at https://wiki.openstreetmap.org/wiki/Access_provisions_in_the_United_Kingdom#Public_Rights_of_Way
