Methodology & limitations
Sales estimates use an additive Boxleiter-derived heuristic against public Steam review
counts. They are not authoritative sales data, and the fixed display range
is not a statistically validated confidence interval. Actual results may fall outside it,
especially for deeply discounted or bundle-heavy titles. Algorithm version
v1.0. Read the exact method and validation status.
Sales estimates for Bittersweet Birthday are not yet available because its Steam review count is still being collected. indielist publishes a fully transparent, white-box Boxleiter-derived method rather than a single black-box number, so every estimate can be inspected factor by factor once review data lands.
