That's sieving P-depth. I think he wants to know what n-range that it sieves. In other words, does it sieve n=100001-110000 like for Nash weight? I'm not sure about that. Do you remember?

On the P-depth, it does sieve to P=1e6 and then uses a multiplier to estimate a sieve to P=1e12...and to me it's more than a "rough guess" on the number of tests at P=1e12. I've found it to be very accurate.
