I think the randomization is better applied to the individual altitude measurements. As that is what will be complicated by wind and sea motion. The randomization is now applied to the viewing location in this script. And so applies to all observed objects in the same way. But I understand this is not really possible to program into the startup-script. As it should be a post-fix correction.
Personally I would limit myself to the amount I can zoom in on the object (to simulate the amount of wobble in holding my sextant), and guestimate by eye at what distance it is at from the nearest altitude gridline in Stellarium. That means 3 individual opportunities for measurement errors. Increasing and distorting the size of the position-probability-triangle. Instead of a single offset applied to all observations making you calculate the position of where you are NOT at.
