Hmm, a question on this - I have "strength 20,000" planetary sensors. 50 installations, I guess they are strength 400, either way the economy screen tells me they are strength 20,000. As I understand how passive mechanics should work, this should mean that I detect a strength 1000 object at 20,000,000,000 km right? Well, I find that when I "show passive sensor ranges", it shows that it will detect a strength 980 object at around 3 light years. Is this working as intended and I've misunderstood something?
