80% band, log scalemid, reviews × k

Owners ≈ reviews × k: 62,857 × 60 = 3,771,420. 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, ×0.24 to ×2.43 of the mid); over 292 announced figures the model is typically within ×1.6 and 79.5% of them fall inside the band.
