Changes are recorded the night they appear on the official pricing page, unless corrected to an earlier confirmed effective date. The tier label shows the model currently in that slot; historical rows are never rewritten. Full history: the charts.
About these numbers. Prices are checked nightly against the official pricing page and recorded in an append-only history (data through 2026-08-21). Last hand-verified 2026-08-21. List prices only: promotions and limited-time discounts never enter the history. If a number is wrong, the correction is published, not buried: see the methodology.
