I'd never doubt your calculations. But the N ranges I am interested in are larger than the Primo limit. So "the polysieve way" is the only one I know to get large provable triplets or quadruplets.

When sieving for a 6tuplet, you eliminate a lot of possible 5tuplets because +8 or -8 gets sieved out. So you probably will have to use a larger candidate range. Does it...

I didn't go for a number that is N-1 provable. I was looking for quintuplets, so Primo would be needed anyway. The problem is that the sieve files get very sparse when you search for n-tuplets....
