Times
Minutes in a small spiral tank with intermittent agitation, copied from the datasheets linked on each row.
Starting points, not guarantees
Every number below comes from the manufacturer's datasheet listed at the bottom of this page. Sheets get revised, so check the current one from Ilford or Kodak before relying on a time, and test a roll first. Temperatures other than 20 °C are highlighted.

Agitation: Ilford's pattern is four inversions in the first 10 seconds, then four in the first 10 seconds of each minute (more on reading these tables). For continuous agitation Ilford says to cut times by up to 15%. Kodak's summary sheet lists D-76 without a dilution, shown as “—”; it also warns that times under 5 minutes may develop unevenly.
