Actually I still do not understand how it works and for what purpose. Ok just single jump, but I read here for "reaching points that otherwise would be impossibile/hard to get". No idea ...Seriously, don't waste your precious jumponium materials on this unless you are really in a hurry. But if you must, it's worth trying the level 1 to test the mechanism .You may also consider if you have enough for a return jump, lest you stray into the dark void from which no traveller returns without a return ticket or access to a fuel rat.
