I have to tread carefully because I am likely the weakest mathmetitcian that ever posted here. There have been several posts about errors in the "cocked hat" and like this one, all over my head. Pun intended. But to my point. I have done over 6000 sights with an artificial horizon and always used the obvious center of the hat triangle as the fix. It is always within 5 miles or so of GPS. There is uncertainty of course, but in mid ocean, does it matter? If it's within 10 miles you're OK. Right?
