After the outcry of so many players about violent traffic swings in their "isolated regions" they supposedly worked alone, FD did heavily rework the "bucket" recently.
Based on what I saw, random 1-4 missions won't do frick to a system now aside of 0.5-1% movement. And +inf now only measure the distribution internally, but doesn't help the bucket. In short those players that complained over randoms coming through every 3-4 days now have to work extra hard the other 5 days of the week for 2 days of "defense". I personally don't care. Now even the border regions of low pop and traffic need a lot of work to move a lot. This only means our borderwatch has more freetime to focus on actual systems we want to clean of pirates with a bit more workload, but we partially don't even have to basic prep defenses anymore, even against 1-2 peoples focused effort. So what, we lose 1% per day. Big deal...
