I have certainly seen evidence that these are simply being armchaired
with no particular overview. I had spotted some locally and decided
against changing the tags until I had the chance to review and map them
properly.

Certainly no race against time for this one, crayoning vast areas of
the countryside orange without considering field boundaries has no
particular value IMHO.
