I know that paragraph from Dutton. There are also so-called fix bearing methods described in Crawford and Saunders, Reeds and Mixter. Of course, it is described in Bowditch (see TAble 7) There are also so-called 7/8 Rule, Bow-Beam rule, Doubling angle Rule, Special Angle Rule (34deg-64 deg, 38 deg.-74 deg, 44-88, 60-113 which gives distance abeam equals distance run), or 38-52, 52-74, 63.5-90 which gives distance abeam equals twice distance run), etc. The formula I suggested just make one more way to calculate distance off, NOT TO REPLACE ALL THE OTHER ONES. If someone got that impression-I'm sorry for misleading. Again, it is another different way to calculate the distance which give the flexibility of not looking for a special angle combination. It is not a double angle case.
