I also test-sieved 32/64, and a sieve range of 15-225M should yield 410M relations. I think 33LP is substantially more efficient, and I wish to continue to collect data about required # of relations for these small 33LP projects.

I would like to do the LA for this number.

May I call a moratorium on adding new 14e entries while we have 12 essentially fully-sieved ones without a post-processor?

[frmky]

I'll throw some cycles at helping to clear this backlog.

You can easily do that since the majority of the 14e tasks are done by Gridcoin users which are sieving randomly. By not feeding the 14e they will process more 15 and 16 tasks.

Or ask Greg to give less priority to 14e tasks on the overall balance, can’t remember what was the % breakdown for each application.
