Effectiveness Metrics: The standard provides metrics for ECDA program performance: detection probability, false-negative rate, excavation hit-rate (ratio of excavations confirming corrosion), and mitigation follow-through. It encourages continuous improvement via feedback loops between verification results and modeling. nace sp0170 pdf 2021
