Before you quote this

Each of these is measured from the data rather than written down, so it stays true as the data changes.

The producer states no release date for each period, so publication dates here are derived from the period end plus its typical lag. They are approximate and labelled as such wherever they appear.

A definition is often only clear beside its siblings.
