The confidence score blends signals such as: how many comparable layouts contributed, spread of internal retails, freshness of the quarter, and agreement between row-level checks and the engine.
High confidence means the guide's own data picture is coherent for that row. Low confidence means you should treat the number cautiously, widen your research, and document your rationale if you rely on it professionally.
Confidence does not ingest sold prices from Autotrader, eBay, or auction houses. It is not a probability of sale.
Open the confidence panel on the result row for the narrative breakdown. If confidence is low, cross-check with recent local listings and your trade network before committing.
What the confidence score means
Confidence summarises internal consistency of guide data - not whether you will achieve that price on the open market.
