I can confirm this behavior. I just updated one of my computer from v30.8b17 to v30.10b4 and the automatically chosen bounds for P1 tasks changed from B1=802000, B2=192756300 (on exponent 117256537) to B1=862000, B2=357135900 (on exponent 117257207). The program is set to use 84G RAM and the actual usage is similar before and after upgrading.

Can you please confirm that PRPCF will be done automatically, and before the factor is transmitted to PrimeNet? Same way that P1 results are only sent after stage2 is done, or ECM after all curves completed, the PRPCF should be considered an extra stage of the factorfinding. There seems to be vocal support for this to avoid all possibility of poaching by those keeping a close eye on recentlyreturned factors.

Then the PRPCF takes place  unlikely anyone will notice the factor and start a PRPCF before you. If ContinueECM is set, then rest of the ECM is then run.

Extreme coolness. Thanks. There is a reason many have trusted George's code for many (many) years...

I think it is meant to apply to exponents small enough that that is extremely unlikely. George hasn't indicate yet what size exponent this is, but surely should make the limit configurable soon. The people that have a right to feel 'peached' are those who put in a lot more cycles than a PRP would take, which is usually ECM and the exponents practically always less than 5 million (such a PRP takes less than a day even on the slowest machines).

Maybe my first really bad typo here ... (As for that exponent threshold, he has not yet updated the documentation at all, which is not unreasonable right now, and I could not find it in the source.)

My computer just hard restarted after running the latest version for a while, and this seems to have caused the prime.txt to be wiped clear. Thankfully did have a backup of the prime/local.txt files

I noticed possiblyundesired behaviour from v30.11 doing autoPRPCF on M41413. This exponent has 6 factors known since 2016 or earlier. JacobZ did a P1, presumably(?) without specifying the list of known factors, and found a composite factor of the 4 smallest/oldestknown prime factors. Prime95 v30.11b1 then did an immediate PRPCF on those that 1 composite factor (which gets transmogrified to the 4 prime factors by PrimeNet on submission), but now the PRPCF history section shows 4 tests with 6 factors, and then a morerecent test against only 4 of them. I assume it's partly the user's fault for doing P1 with specifying known factors. But what if he had specified known factors and found a new one, would Prime95 do the PRPCF on the list of known factors + new factors? Is it smart enough to check factorfound results against the list of known factors, divide out the known ones and be left with only previouslyunknown factors (even, possibly, if the unknown portion might potentially a composite of 2+ new primes)? Is it possible for Prime95, when finding a factor, to submit the factor result (as it does already) and then ask PrimeNet for a proper PRPCF assignment for that exponent, with the full list of all known factors (which will guaranteed be prime factors only, coming from primenet). If the machine is offline (transient or configured) then it can fall back to doing the autoPRPCF based on what it knows, but it would be better if it had full data to work with.
