I have sieved a little bit more than I should based on the LLR/NewPGen breakeven point  according to my test it should be 8'25" for n=350000, and I sieved until ~9'30".
Same applies to 200250k and 250300k ranges  in first range I have found
zero primes (the number of candidates was ~8000), in second range I am currently at ~269k and still
no primes
So I guess it's just my luck to pick such a "nasty" k...
