1 out of 16 for a trebling of n-range seems notably low. Low enough to make sure there wasn't a mistake somewhere?

It is as it is, bad luck, I have only one base left with the old llr 3.8.21, all other are running now with llr2 and a Gerbicz check which detects bad hardware and rerunning from the last check point. We have already planned some double checks, one is running at the moment.

 2022-11-22, 03:09 #4152 gd_barnes     May 2007 Kansas; USA 2·53·109 Posts Stand-alone, these last two bases for n=100k-300k are not extremely unusual. Taken as a whole for the year of 2022, what has happened is extraordinary. We had ~20-25 bases with 2 k's remaining, all of which had no primes for either n=300k-500k or 400k-500k followed up by R88 with 0 out of 19 for n=250k-500k. After the above, there were some bases with a normal # of primes, and then we had these two for n=100k-300k: R711: Sieve depth: 1e15 # of tests: 71198 expected # of primes: 3.7 actual # of primes: 1 S954: Sieve depth: 1e15 # of tests: 60181 expected # of primes: 3.0 actual # of primes: 2 (k=119 had both primes) By themselves, nothing to be alarmed about. It's just become a recurring theme this year. What sticks out at me the most about R711 is that there were 8 primes for n=50k-100k but only 1 prime for n=100k-300k. This happens often on the project due to sheer randomness but it's just been strangely frequent recently.
