Just in case somebody in the future is curious about this topic, I finally bought the advanced jump drive systems skill and it is sweet! One skill level gets you a nice round number of 65 length added so after you train it to lvl 1 you have 155 navigation points(AU’s? superkilometers? light years?).
Now, after you save up all that loot and buy the skill you may think you will be sitting pretty, but it took 2 days and 2 hours I believe to train it to lvl 1. Of course, now that I have it trained, it sure makes it easier to take Dryden loads that are over that magical 90 number. On the other hand, my fuel gets sucked down a lot faster too!
