So for the third time, please add another 10M Q. Thanks.

[QUOTE=richs;513160]So for the third time, please add another 10M Q. Thanks.[/QUOTE]

It looks like the last 10M Q only added about 2.6M unique. Perhaps a bit more would be in order.

With lims as low as they are (FRMAX 33500000/FAMAX 67000000), and Q already at 170M, this job may need someone to do some offline 15e sieving below the Q=12M starting point. Yield of 0.26 is pretty terrible, but yield at low Q may be enough to salvage the job.

You are correct [B]VBCurtis[/B]. I was going to ask [B]richs[/B] if he wanted to do 256128979_23m1 instead and I would take over this number and perform some low level sieving after I got back in town next week. One or both of the "lim"s should have been increased in hindsight. My fault.
