My developer chart

Times at 20 °C, small tank, inversion agitation. These are my numbers for my water and my taste, not manufacturer data.

Agitation: first 30 seconds continuous, then four inversions at the start of every minute. For stand development see the notes on the front page before trusting that last row.
