Moth, I know it was a long time ago when you were there, but did you visit the stone row to the east?
I had a lovely few moments at this circle yesterday. As you say the battered condition really does add to this place in an odd way. It's almost perfectly f*cked!!
This is definitely a place where you ain't gonna get interupted or distracted ... except by sheep ... ahem
(One of your images does have the wrong direction on BTW - I think the one labelled "west" should be southwest - I'll check my pictures vs. the map later and let you know :-)
