NotationDRCDRC
FormulaDRC=∑b∈BucketsDRCb\displaystyle DRC = \sum_{b \in \text{Buckets}} DRC_b
DRCb=max⁡[(∑i∈LongRWi⋅netJtDi)−HBR⋅(∑i∈ShortRWi⋅∥netJtDi∥);0]\displaystyle DRC_b = \max\left[\left(\sum_{i \in \text{Long}} RW_i \cdot netJtD_i\right) - HBR \cdot \left(\sum_{i \in \text{Short}} RW_i \cdot \|netJtD_i\|\right); 0\right]
