How conditions work
Each number names its station and its time. Dolphy summarizes those numbers and does not add any.
How fresh a reading is
Each source has a usual update time, listed on the sources page. A reading older than twice that time is labeled stale. It stays on the page, and it is left out of the score.
How the score works
Payment never changes site order, the score, or which reading is shown.
Conditions are informational, not a dive plan. Check with the site or operator, dive within your training, and make your own go/no-go decision.
