FAQ: What “signals” means here
Signals are aggregated observations used to position a product among its peers in a given tier.
FAQ: Why price tiers?
Price tiers keep evaluations apples-to-apples.
Products are measured only within their own tier, never against unrelated price classes.
FAQ: Interpreting uncertainty
Confidence notes and evidence depth indicate the level of uncertainty.
When gaps exist, results lean cautious instead of filled-in.
