Bob, Looking at your diagram there are a coupe of practical notes that must be made. First the distance and angle measurements must be taken from a point in the plane of the parabola, i.e.. under the limb.
Question: Looking at the illustration I see that angle 1 (a1) is in a different direction than are a2 and a3. Is this accounted for in your calculations? Need it be listed as an angle > 90 degrees. In the diagram, must you be to the left of point d2. How do you deal with the different points being on the opposite side of the person making the measurements?
