We establish a strict two‑stage calibration‑and‑prediction protocol: the critical escape velocity and the dimension‑specific coherence factors and are determined once from a small calibration subset and then fixed. Blind prediction against the full set of 19 materials—spanning five orders of magnitude in and including systems never used in calibration—shows that predicted values deviate from experiment by no more than a factor of 1.10 after applying literature‑derived microscopic corrections (, , ). The previously reported 4‑fold overestimations for heavy fermions and 2.5‑fold overestimation for FeSe are eliminated by these externally sourced corrections.
