Curated values teach the governed relationship among flow, concentration, and mass per day. They are not operating targets, design criteria, permit limits, process recommendations, certification weighting, or claims about a specific plant.

This Draft family uses selected mathematical facts only. It does not reproduce an official formula sheet or claim how an official exam weights topics.
