One more idea: It may make sense to stop this sieve now, run 69M until 300P, and then add 56M to the 69M sieve and continue with 59M up to 800P or more. I thought this should have been done with 23M added in to 36M 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.

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