Both the explanation from Kuikueg and Neuro worked great for me. But still, it is the particular method for ownship constantly moving that I was concerned about.
Not just because of the workload, but also this method relies heavily on the little triangle formed by 3 bearing lines to determine the extrapolated 4th line. In practice, this triangle could be pretty far away or relatively small that would contribute to plotting errors. And the two anchor points that the extrapolated 4th line passes through are always close to each other, making any plotting error to be exaggerated.
By changing your mind to plot relative motion, you can use the stationary method which is less prone to plotting error.
You can also use the formula and a calculator, or a disk. But I guess people using this method really love plotting.
