Hi Bob,
Like David, for me you're not moving the 1624 LOPs properly. You should move them approx. 10nm further in the WSW direction, for a total move equal to your DR1-->DR2 vector.
Rationale: wherever along the LOPs you were at 1624, then that point at 2107 has moved per your DR direction and distance. Therefore the 1624 LOPs (which are the sets of possible points where you were at 1624) must be moved by your DR1-->DR2 vector i.e. your estimated move between 1624 and 2107.
All 3 LOPs at 2107 are then still not all crossing at a single point, but the cocked hat is much smaller.
I hope this helps!
Christophe
