Also, the distance away from the approaching enemy fleet entirely determines whether you will be able to intercept them or not as they approach you and you approach them. If you move the same speed, you can end up moving into the sector that the enemy is on the same day that they move into the sector that you were just in (or even a different sector). In this case, you will never be able to catch them until they stop, or get slowed down.
