Mjmw, the trick on blue stars is to exit early and make up the lost fuel on the next M class. You can actually scoop more than you used on the last jump at M stars. Yeah it's not relaxing at all, and a 10 hour slog would get pretty iffy. Remember, the jumps don't always have to be perfect since there are a LOT of M class stars to make up the difference, and you get a free scooping reprieve every time you replot (hopefully only once every 1000LY).
Yeah, but with a 2 or 3 jump tank it can get very sweaty relying on the next one being an M-class star
