How this story is written
- Every sentence in quotation is an edition's own: its summary, then its findings in the edition's order, the first for each of its figures, leaving out a finding whose figures are all already quoted, at most 3 for each edition and 4 editions for each section. Nothing is chosen by hand.
- Every figure links to the place in the frozen edition that states it: the table row or figure it is read from, the finding, or the edition's summary. A frozen edition never changes, so each link reads the same number later.
- The sentence setting one month against the one before uses a figure only where both months measured it the same way, and says "rose" or "fell" only when both months read the same number of platforms' job boards; otherwise it gives the two values side by side.
- A report with no edition for the month is left out, and so is a section with none.
