National aggregates: CGPI value, WoW/MoM change, mean and median city basket cost, cheapest and most expensive city.
Basket cost is the sum of each matched item's most recent observed effective price (sale price when on sale, otherwise regular) within that banner that week; cheapest-banner rankings are restricted to near-complete baskets (≥48/50 matched items) because missing items deflate basket cost. Observations are append-only; the index is recomputed from the full observation history under versioned normalization code, and the superseded v1 fixed-base series remains available via the API. See methodology for the full specification.
