looking at everything on the list, i can confirm a lot of it. one thing to add, Pelagic Clay drops in Sea of Jade 2

I have done most of my runs with 185 surveillance and 200-205 ships. I have gotten 0 interesting items at 185 and plenty of good items at 200+ surveillance. I see someone above said 195 is the sweet spot and I was building towards that to test myself.
