Since 6-9M has barely started, it may be wiser to do 6-10M or even 6-12M for greater efficiency. Is there a reason not to run a bigger n-range?

One more idea: It may make sense to stop this sieve now, run 6-9M until 300P, and then add 5-6M to the 6-9M sieve and continue with 5-9M up to 800P or more. I thought this should have been done with 2-3M added in to 3-6M from 100P to 150P.

I shall check how much we can sieve.

Think about that we sieve for DC !!

We test all proth k's 3<k<10000

We sieve riesel/sierp (+1/-1) 5<k<10000 3M<n<6M. I have todo some tests if we can sieve more but I think some older card can't do that.

We also sieve 6M<n<9M manually now. http://home.comcast.net/~jimb_primegrid/ppr9M/

So if you calculate with DC you will see that we have lot of sieving left before we reach optimum
