The label "Regional Market" implies concentrated retail demand; the rule admits the single-anchor case. The headline count is therefore inflated by exactly the cases that carry the least decision value for site selection or investment. **The count reads as an artefact of the floor, not the geography.** A reviewer can move the count up or down simply by arguing the floor, which is the classic sign that the threshold — not the data — is doing the work. This is the same failure class as the clustering parameter sensitivity documented in [[catchment-ranking-methodology-v3|the V3 catchment ranking methodology]], where parameter sweeps move the North American cluster count across a wide range without any change to the underlying retailer data. **The count reads as an artefact of the floor, not the geography.** A reviewer can move the count up or down simply by arguing the floor, which is the classic sign that the threshold — not the data — is doing the work.

The geocoding-confidence field does not resolve this. It is geocoding precision — specifically the quality of the boundary assignment — not market quality. It must not be presented as a ranking or a quality signal. @@ -99,6 +99,6 @@ Two honesty notes belong in the platform's documentation alongside this table: ## See also - [[about-regional-markets-system|Regional Markets Intelligence System]] — the full dataset, tier system, and qualification method this article's definitions build on - [[catchment-ranking-methodology-v3]] — how tiers and the planned strength score are computed for each co-location inside a Regional Market - [[catchment-ranking-methodology]] — how tiers and the planned strength score are computed for each co-location inside a Regional Market - [[trade-area-methodology]] — how the trade area for each co-location is defined - [[spend-population-provenance]] — the estimation chain for population and spend figures attributed to each co-location
