Here is a link from the 2017 thread mentioned earlier. There is alot of good info in it. My amateur advice would be to start with your best guess of a D/R (Last known fix, or just make one up like Moitessier did) and do several iterations of your sight reduction using the resulting fix as a new assumed position. Within a few iterations the LOP's will stabalize around your true position.
