How the figure is produced
- Every forecast publication writes a new dated row rather than editing the previous one.
- Database rules reject updates and deletes on the table, so the history is immutable once written.
- The register links each revision to the period it estimated and the confidence stated at the time.
Awaiting verified data. The table appears here once the current record loads.
What this figure cannot tell you
- The history starts from the date logging began — earlier forecast changes were not captured in this form.
- It records what was published, not the full internal working behind each revision.
