... uses the performance objectives in Step 5 with the actual response times for each of the four target outcomes -- Assess, Manage, Rescue, and Control -- shown in Table 18. For each scenario, the ratio of the actual average response time to the goal response time for each target outcome is calculated and the value for the RTF is assigned using Table 19.
