Thanks. I made most of my early credits mining void opals and LTDs in that system, before they were nerfed a couple of years ago.
I've mainly been focussing on "virgin" systems like this. It might be an exceptional one, but it started off at just 35 targets. That has got me wondering just how far off some of the numbers are, and potentially how many ports are being missed. The biggest aid for me has been the new system summary feature, which should give the correct number of dockable ports if fleet carriers are filtered out, you're in a small ship, and there are no active conflict zones.
I have a feeling this exercise is going to take quite a bit longer than anticipated!
