status update for k=323

Testing at n=1.05m, no primes

Note: FFTlen increase from 65536 to 81920 between n=1.051m and 1.052m. Testing now takes 35% longer.

You might want to give it a more positive approach. If you look at the bases with 1 or 2 k's remaining:

Riesel bases: 22, 23, 26, 27, 49, 72, 93, 94, 100, 109, 110, 123, 160, 170, 177, 181, 704,...
