The problem with the cords (at least at first sight) is that they are only accurate to the 100'th of a second (and not a 1000'th) . They could be way off, maybe up to a 1-2 tenths of a mile (as XRock and I found out up in Utah on our hiking trip).

Just look at your map software and go from 35° 53.170 - 35° 53.179 and see how far apart they are (then you add in the West cords and you could be way off).

It'll still get us in the general area at least.
