80% band, log scalemid, reviews × k

Owners ≈ reviews × k: 9,278 × 60 = 556,680. k is the prior for 2013 and earlier, because no cell in that band has five announced figures. The band applies the model’s own residuals (10th to 90th percentile, ×0.38 to ×2.32 of the mid); over 182 announced figures the model is typically within ×1.5 and 79.1% of them fall inside the band.

Followers by day · 1 sampled day since 6 Sep 2026 · at most 90 days

One daily sample so far (6 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 6 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, 00:40 UTC. No follower-to-wishlist ratio is applied. How this is computed. Data by SteamPeaks.com.
