Owners ≈ reviews × k: 6,732 × 48.84 = 328,777. k is the median of 72 announced figures for games released 2021 and later at $10 to $30. 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.
