I've noticed that when first transiting from one gravity well to another you leave from some "random" point but arive roughly centered on the connecting line. So I was hopping I could edit the lanes to always do this.
That's actually not true. You can arrive rather far out from the center of the phase lane your traveled on.
I thought it was the father away from the lane you were on the exit planet, the farther you'd be at the destination, but its been a while since I've abused this.
