I "think" I understand this point. I must study it a bit more.

As an aside, looking at a random machine, I find that it returned in 15:05 with 28074 relations early on. The last iteration took 7:30 to return with 6624 relations. Effectively, that equates to only a 50% reduction, roughly.

Going all the way to I=15 is a 4x increase in memory, while A=28 only doubles memory needs. While your yield is way down, I don't think sec/rel falls in the same way. That is, workunits are going by more quickly. EDIT: If there is a range of low Q you didn't do, I'd do those with I=15. Say, Q=100k to the Q-min you selected. You could even use A=30; desperate jobs call for desperate measures!
Although my most recent update isn't that old, tasks.A is not recognized and none of my clients are newer than the newest server. It would be quite a task to update all of them.
