Will k=10052000 be for all ks or just those not reserved by others?

All k's. No worries. I know you're searching a few k's for k=14001500 for n>350K. We'll start out at n=50K sometime in Jan. It will only be several weeks to a couple of months later that we'll likely start some top5000 ranges after we've sieved further. Like we've done with our other drives, we'll inform people ahead of time and it will be up to them to stay ahead of our drive(s), which will progress relatively slowly for ~500 k's. It should be very easy to stay ahead of our drives, even with a small amount of resources. Alternatively, once we start top5000 work, you could give up your reservations and search the ranges with us instead of RPS. Then you won't have to sieve your own ranges anymore! The main benefit about searching with NPLB is that everything is sieved in one big glob at once resulting in a huge increase in sieving efficiency and very long times between when sieving is needed. It also means that only a selected few who really enjoy sieving do it. Soon we'll be searching ~350 k's for n=600K1M; all fully sieved already and ~500 k's for n=50K500K; the lower nranges which are already sieved enough with some more sieving needed and ongoing for higher nranges.

Personally I don't care what RPS thinks. They own nothing like we own nothing. People or projects cannot claim ownership of segments of the math world. They can only coordinate efforts on them. If there are some k's < 300 that get well behind, we'll search them. But as of right now, other then k=5, most of their k's are in decent shape (mainly thanks to our 4th drive, lol). k=5 should be at n>2.5M by now but after Benson picked them off twice because they had searched it much too slowly, we won't go there. That said, I'm all for avoiding too much controversy and I don't want to involve others in any overly controversial effort in the future. We won't be doing large #'s of k's < 300 at once anymore. Just 1 or 2 k's here and there after follow up with specific individuals as needed like I did with Beyond on k=47 and 53, which were at n<600K a month ago and are now at n=1M with 3 primes found in the range searched. That worked out well and Beyond was perfectly fine with us filling in the range since he had previously searched some ranges for them for n>1M. Gary

there's no waste of time!
you're searching ranges never searched before and filling a gap for k=1009. and NPLB will doublecheck these ranges like many others before, because there're many examples when primes were missed although the ranges were said completly searched! continue your work!

Yes, please continue your work. The same thing applies to Chris (Flatlander) who is doing quite a few k's 14001500 for n>350K. We'll just be doublechecking that work also. That's what NPLB does because as Karsten said, many primes have been missed in the past even though ranges have been reported as complete. An excellent example was my recent prime find for k=47 at n=~540K. The k had been reported complete to n=582K but I doublechecked it starting from n=210K and found the missing prime. No prime left behind! Gary
