The Sensitivity attribute is in the Sliding Window Alg Advanced section of the DLLR object UI. It is a fine-tuning factor that provides three user specified levels: low, medium, and high. The high sensitivity setting provides for more aggressive load shedding than the low setting. Figure 1 shows an example of how sensitivity affects the amount shed.
