3a) First do a run with PFGW to dispose of all the small primes (see attached script)
3b) Then sieve the remaining k with srsieve
4) when you have sieved deep enough, switch to LLR or phrot.

Enjoy, Willem.
Thanks for your answers. I have a few more questions though:

2a) This program by R. Gerbicz (covering.exe) requires an exponent. What is the meaning of this exponent?
3a) How is PFGW related to that attached script?
3b) How do you know if you have sieved deep enough
4) How should you determine if you should use LLR or phort?

One of the reasons I ask this questions is to lower the step for people interested. Sooner or later a sticky topic with the needed info could be handy and interesting for potential sievers or prime hunters.
