 - Outturns are re-computed in near-real-time every 5 minutes after the end of the half-hour for 3 hours, to allow for late arriving sample data
     - If all data ingestion pipelines are running smoothly, this does not result in any retrospective revisions
     - If some near-real-time sample data is late arriving, the outturn estimate will be revised at the next update
-- Outturns are re-computed on day+1 (typically between 10:30 and 10:35 and again between 22:30 and 22:35) to make use of sample data which only becomes available on day+1
