Iterated paired-fiber deformation from the new N=3825 record. The 50-set at 3825 is exactly B+(0,25) with 25 pair bases. Write each base as m*153+r and replace 153 by 156, keeping the offsets r fixed. Remarkably the resulting 50-set modulo 3900 is still solution-free, so no repair is needed. Score 50/sqrt(3900) ≈ 0.80064077.
