Serge was referring to 92M total including duplicates when you start sieving at q of half the factor base limit. You should be able to build a matrix at about 78M unique, but a few more will improve it. I usually get at least 83M - 85M unique before starting the LA.

For small numbers, if what you're doing works, keep doing it. For larger numbers, I usually start sieving at about half the factor base limit, sometimes a bit below, then keep on going until I've got enough. You can also start really low and sieve to about half the factor base limit, then jump to above it. Sieving the entire range below the FB limit, though, leads to tons of duplicates as you discovered.
