For the 12300000 area sr2sieve is telling me to expect 4.31 factors in a 1000G range. For the 1498000 area it was 37.5 factors in a 1000G range. It does run the 12300000 area 20% faster, but I hope the 4.31 factors in 1000Gs is not correct. I've only run a few hours in the new range so don't have any real data.
