Followers by day · 1 sampled day since 7 Sep 2026 · at most 90 days

One daily sample so far (7 Sep 2026); the line draws with the second.

Followers are the community hub’s member count as the store page shows it, sampled by SteamPeaks since 7 Sep 2026. A gain is the newest sample minus the sample the window back (within twelve hours for one day, a day otherwise); where that older sample does not exist the gain is missing, never zero, and the day the window opens is given instead. Figures from the hourly momentum job, run 8 Sep 2026, 15:45 UTC. No follower-to-wishlist ratio is applied. How this is computed. Data by SteamPeaks.com.
