- Notes
- DCS RT_RT.xls, 'Revision Triangle for Quarterly and Annual GDP estimates (Last updated 15th September 2026)'. TRUE vintage mechanism: each column is a real DCS release date (read from the sheet's own Excel-date header), stored as the observation vintage, so the same period accumulates one row per release that reported a growth rate for it - the schema's vintage mechanism exactly as docs/conventions.md describes. Compare with RT_Summary.xls, which gives the same series by NAMED stage instead of by date.
