Test-sieving on the -a side suggests Q from 20M to 130M will yield almost 250M relations:
[code]Q=20M 0.079 sec/rel, 2768 rels
Q=40M 0.097 sec/rel, 3073 rels
Q=60M 0.115 sec/rel, 2143 rels
Q=80M 0.124 sec/rel, 1648 rels
Q=100M 0.140 sec/rel, 1728 rels
Q=120M 0.152 sec/rel, 2579 rels[/code]
I'm working on a hypothesis that really low mfbr/a allow us to build a nice matrix with fewer relations than one might expect. I'll handle the matrix, as I want to play with the data a little bit.
Gimarel showed the way in the CADO thread with params for C100 using 27LP but mfba/r of 48.5; I've extended his work up to 135 digits, with each test completing in 15-20% less time than previous efforts at the same input size.
