This job name is going to collide with that of a previous job (iteration 11 of AS 79^99).

Suggest we incorporate the iteration number, 22 in this case, into AS x^y so we avoid such problems going forward.

Any objections? If not, could posters of these jobs include the iteration number somewhere in their post?

ETA: no responses so I’ll add iteration number to AS x^y type jobs for all future factorizations.

Test-sieving indicates Q from 50-400M on the -r side will produce around 660M relations.
I will sieve Q=35-50M locally on a larger siever, and swellman has agreed to handle the matrix.
Code:
#Q=50M	3013 rels, 0.251 sec/rel 60 spq
#Q=100M 2231 rels, 0.317 sec/rel 54 spq
#Q=150M 2080 rels, 0.374 sec/rel 58 spq
#Q=200M 1765 rels, 0.412 sec/rel 55 spq
#Q=250M 1572 rels, 0.428 sec/rel 51 spq
#Q=300M 1493 rels, 0.448 sec/rel 51 spq
#Q=350M 1323 rels, 0.500 sec/rel 51 spq
#Q=400M 1256 rels, 0.464 sec/rel 45 spq
1kQ intervals tested.
Now in LA. With the relations from NFS@Home for Q 50-400M, plus those from Q=35-50M sieved by you, this job eventually produced 487.1M uniques. TD=122 produced a 27.48M matrix with an ETA of 923 hrs at 0.2% complete.

So factors should appear approximately Dec 3.
