10 jumps every 100? I don't think we are taking the same highway ... If you use Spansh to plot a neutron route with a 65 ly range ship starting at Jameson Memorial you end up with a route that estimates 109 jumps. Adding the occasional refuelling stop adds 20 more jumps at most. Add another couple of short stops for repairing the FSD, you conservatively end up with something like the time equivalent of 140 jumps using the neutron highway. Even if you could jump in a straight line without stopping to refuel, jumping from Jameson to Colonia would take you 339 jumps. Adding that it takes slightly longer to neutron boost than just jump, I would say you shave off about 30-50% of the time by travelling the neutron highway. This is of course also going to depend on your familiarity and proficiency in neutron boosting and plotting your next jump etc.
So I just looked up spansh, I have never seen that before. Thank you for that Orodruin! I was wondering what the hoopla with the neutron boosting was all about, I never found it to really change my travel times all that much. I would just enable jet boost in the galmap, I never knew about spansh. I'll check that out for sure!
