I may help some more later in the week, if it struggles to get to Tier 2 by Thursday, but Tier 3! no thanks, Mission Contracts is only for EDO isn't it? (console player).
OK, so I have made a lot Cr getting 7000+T, but will make even more than that going back to plat/os/pain mining. It is a lot more relaxing than A-B-A CG (and yet another CB hauling CG to come next week (yawn!))
AND what is brilliant, is randomly jumping my FC 1000+LY (3 jumps while cooking dinner IRL) and then using mining 'Conda with Fuel Scoop to explore with DSS and finding undiscovered and unmapped pristine metallic and having no NPC's turn up when changing to mining, as system is not populated, so I get UC data and Plat for my own FC (I do open the FC to all pilots, in case any turn up nearby looking for fuel/repairs, and close it off before I jump back to sell mined stuff).
