In a dark start game, you may have stars at the beginning of the game that are outside of your scan range but within your jump range. However, you cannot see this until the game actually begins. I like to set my moves for the start before the game starts just in case we end up with a bad production time. However, there might be a star that you might want to rather jump to for tactical purposes.
Why should I have to wait for the game to start to see that star? If it is a private/custom game, okay. But standard games should have scanning range = jump range in some way.
