I don't know if that will count as a reservation limit, but I will test both until I find a prime for each

No.

I'm just curious. What range do you sieve when you start a potentially open-ended job like this? How do you determine an optimum sieve n-range and P-limit?

For this "project" I have sieved all initial k's together using sr2sieve until n=1M. As for P-limit I go with classic approach: measure iteration time at approx 2/3 of a range, and when sieving efficiency is below LLR-test efficiency, I freeze the sieve. Right now I am sieving S10 in the range 1M<n<2M, and continue testing R10 till n=1M.

Did I mention I hate your speed MyDogBuster (I can't match up yours, that's the size of it)?

I'm just trying to get the 2M-5M's to 100K like the <1M k's.

It will be nice to get all of them to 100K.
