  "abstract": "MOND predicts that the baryonic Tully-Fisher relation (BTFR) has an exact slope of n = 4. Two independent 2026 analyses of SPARC galaxies reject this prediction at ≥4σ, finding n = 3.47 ± 0.10 (135 galaxies, ODR) and n = 3.50 ± 0.11 (175 galaxies, MCMC). We show that a mass-dependent MOND acceleration scale predicts n = 4/(1+x), which is necessarily less than 4. For x ≈ 0.15, consistent with our independent measurement from rotation curve fitting, n = 3.48. One equation, one parameter, two measurements explained. The BTFR slope joins the cluster mass discrepancy as a second independent line of evidence for mass-dependent a₀.",
