Signals are the observed metrics gathered from the market.
They’re aggregated to determine tier-relative positioning.
FAQ: Why price tiers?
Tiers organize products into comparable groups by price.
Each product’s position is measured against its tier peers, not against items from a different band.

Confidence notes and the evidence base make uncertainty transparent.
If information is scarce, outcomes are shown conservatively, never guessed.
