I did about 30 mins on the R2R and then tried something different after 3.3 with the new mapping tools:
1. On the edge of the bubble (find staging system with station services), right where the system names start to become generic and long alphabet soup.
2. Using Krait Mk2 (52ly jump range), pick a system about 500ly away from the bubble (12-13 jumps) filter on A,F,G systems
3. FSS each system along the way and only map high metal content, WW, AW or ELW that have not been mapped yet.
4. Do the same on return trip to station, 12 different systems.
Not even found any new discoveries, just new mappings, my exploration data value ranges from 9 to 12mil per trip.
