This is quite true. Let's say you are all at sea, with no idea what to use as a DR. We'll assume you do know which ocean, so choose a spot in the middle of it as a DR. What you are likely to get is enormously long intercepts. No worries, take the calculated fix position and redo the sight reduction, using that fix as a new DR. That should shorten the intercepts dramatically.
