IMPORTANT NOTE: Keep your jump range below 40ly or so, or you may not get enough scan data for the journey, also something I Did that other may not was have my star types set to: K, M, Non-Sequence (neutrons) and White Dwarfs, their scan data is much more valuable, so setting my Galaxy map to only plot routes through those stars meant i hit as many Neutrons and Dwarfs for the FSD boost but also to get that valuable scan data.
