80% band, log scalemid, reviews × k

Owners ≈ reviews × k: 308 × 67.35 = 20,742. k is the median of 6 announced figures for games released 2014 to 2017 at under $10. The band applies the model’s own residuals (10th to 90th percentile, ×0.25 to ×2.54 of the mid); over 356 announced figures the model is typically within ×1.6 and 79.8% of them fall inside the band.

Followers by day · 1 sampled day since 10 Sep 2026 · at most 90 days

One daily sample so far (10 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 10 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 13 Sep 2026, 01:26 UTC. No follower-to-wishlist ratio is applied. How this is computed. Data by SteamPeaks.com.
