Owners are modelled, not measured: owners ≈ reviews × k, where k is learned per release-year band and US launch price tier from the figures publishers announced themselves (323 used in the fit, on the calibration page). The band is the 10th to 90th percentile of the fit’s own residuals applied to the mid (×0.24 to ×2.44), so read the range, not the mid. Reviews are Steam’s own totals today. A game with fewer than 50 reviews is not estimated, a free game is not estimated because its reviews are not sales, and an announced figure is shown before the estimate wherever one exists. Recomputed daily. How this is computed. Data by SteamPeaks.com.
