After thousands of sights from my front walk, they are almost always a bit south and west of GPS. To what do I attribute this? I would expect errors to be more random. Any ideas? It seems to hold true even with sights off by less than 0.5 min. I don't think the fix has ever been to the east or north. Any thoughts?
Kind regards, Randy
