With my anomaly mod I've tried several approaches. Working with just under 240 anomalies, grouping them in 5 groups (ARTIFACT, CAPSULE, SHIP GRAVEYARD, SPACE JUNK, and WORMHOLE), and 39 sub groups, I continue to tweak. The groups have no weight, and I weigh the subgroups at present in the area of 50, 40, or 30. Individual anomalies I have at weights of 10, 9, 8, and 7. I at one time had all the weights in ranges from 60 to 100, and at another from 4 to 10. What I'm at now works, but could be better. I see anomalies from all subgroups, and powerful or rare ones also show on occasion. All this said, I feel for you trying to figure out how to weight them out effectively. I know this isn't much help, so take this information for what it may provide.
