Hi henryzz
I think you are right, over the long run, deficient primorial offsets are not as efficient as defiicent primorials around the centre point, but they still provide a pretty sparse set of...

For very large gaps I used the sieve_primes routine and then pfgw. Here is a ready to use perl program - clearly change your variables. It produces a pfgw-ready file.
