Also need to factor in GPS uncertainty; although I don't think that is a major issue, unless the fence is set too tight.
The boat won't be right above the anchor, but if I've got 200 feet of rode out, it'll definitely stay within 200 feet of it. If I swing around on a wind shift and it drags 3 feet and re-sets and I'm still within the circle, I'm not worried about that anyway. But if I've moved 20 feet, it'll break the fence and let me know there's a problem.
