65
66/-- Under RS parameter locks, the weight enhancement is bounded.
67
68 The RS-derived weight is: w = 1 + C_lag · (t/τ₀)^α
69
70 With C_lag ≈ 0.09 and α ≈ 0.191, the enhancement (w - 1) is small
71 even for large dynamical time ratios.
72
73 For cluster scales (t/τ₀ ~ 10^20), we still have:
74 w - 1 ≈ 0.09 · (10^20)^0.191 ≈ 0.09 · 10^3.8 ≈ 570
75
76 Wait, this is large! The RS prediction depends critically on the
77 dynamical time ratio. For cosmologically relevant timescales,
