Fig. 5. Robustness of candidate recommendation under varying trade-off coefficients V (0.1 to 0.9). (A) Rank V bump chart showing stable rank ordering across V values. (B) Advantage margins relative to the best candidate using ΔQj=Qj− Q5 (H5 as the baseline), where smaller ΔQ indicates closer proximity to the top candidate. The consistently small ΔQ between the top 2 candidates indicates limited separability (acceptable advantage not satisfied), supporting interpretation as a robust shortlist and motivating Lj -guided closed-loop competency strengthening.
