I tried, it's bad !
You have to pray RNGesus to make a lot of profits.
Before going to Cubeo i went to Pangilagara system. There were a lot of mining mission, some exploitable. In Cubeo nothing !
I spent a lot of money (30M) getting reputation and increasing empire rank in the mean time.
I managed to get a lot of those itens in large quantity, but even if you have a lot of mining mission, very few allow the loop !
Therefore after 5h wasted, 4M Type-9 rebuy after getting blown up by an NPC Anaconda, 4M fines , 30M lost in reputation and so many reputation lost after 20 missions failed, i stop !
(2 time dropping cargo saved me, but the third time i tried to escape without dropping cargo and it was my end)
I was using my Anaconda to try to do cargo wing mission to get more bromelitte..etc.
The video was fun but it's not exploitable !
You were doing it wrong. If ever there was an exploit, this is one of them. Top of the pile. This is worse than Skimmers. At least with skimmers you had to actually do something.
