This pip is that mark on this tide — not the day on the ring.
No marks match this method on this water.
When is moving water in a good hour — not the day. First light and last light are named when the clock is the story. Today’s ring mixes the best mark, the lead fish, and the best window, then taxes the sky. A strong incoming can sit under a weak day if the wind or the fish is off. Calendar cells are a third recipe: range, moon, and the day’s forecast.
