Can you explain the reason for the number of stars drop-down menu in the analyse stars tab?

One might assume that the goal is to get as many stars for the star analysis.

what should be my considerations in determining the number of stars?

Usually about 500 is fine, when doing mosaics it's better to up that to 2000 so APP can register better. Way more is usually not a good idea, it's mainly just to be able to have some flexibility if you as the user see APP having trouble with registration.
