As you raid enemy outposts and defend your own, you gain and lose influence points depending on your outpost performance. You collect points for the duration of a cycle, usually 2 weeks, after which you receive a reward based on your rank.

In the beginning of each cycle your influence is reset to the base level of your last rank. You can check tier specific information and time till the cycle ends in-game in your outpost, “Cycles” tab.

Outpost leaderboards follow the cycles as well.
