I also test sieved equal lims (200M each) but that sieves slightly slower.

Sieve from 34M to 284M on the rational side. That should get about 460M relations.

Test sieving 1k ranges:
Code:
  Q  yield  sec/rel
 34M 2686 0.26608
 84M 2573 0.31101
134M 2648 0.33947

234M 1879 0.40393
284M 1816 0.41399

It looks like this job is well short of relations. Doing the math again the estimated rels are about 350M. I must have been thinking unique relations. This job is going to need another 60-80M Q (or more).

Upped Q by 90M.
