I see roughly the same.

Paul's is about half the speed for 1<n<3M as I'd expect to see for 3M<n<20M. Phil's is about 2.5x faster than Paul's in this low n range.

Now I've started another test for p = 6G - 7G, I'll let it run, submit the factors, and see how it looks.

In the p = 5G - 6G range, I submitted the first three factors, all of which were new! Does this really mean that this area really wasn't sieved for all values of k? Or is this area not reflected in the DB? Or is there just something odd because these three values have been PRP tested? Or am I just missing something?

I am confused.
