• Off-Target Score: Percentage of predicted off-target sites (0-100).
• ZFN Type Factor: Adjustment for ZFN design (e.g., 1 for standard, 1.1 for heterodimer).

This formula incorporates specificity and affinity metrics, derived from studies on ZFN design and off-target prediction (e.g., Isalan et al., 2001; Cathomen & Joung, 2008). It ensures reliable efficiency predictions for practical use.
