There is a new report showing TF results that claim nofactor for a certain range when there is a factor in that range:
https://www.mersenne.ca/tfmissed.php The NF run may have happened before or after the factor discovery. In about 1/3 of the cases the NF run happens within an hour of factor discovery, and might possibly be a poorlyrecorded effort to show that the bitrange was completed even after finding the factor (this is not confirmed, maybe one of the users listed wants to weigh in on how they got so many of these kind of results).

Exactly this; One reason mfaktc doesn't produce a NF result if it finds a composite factor (and the server rejects the composite factor result) so I manually produced many NF results for ranges I had completed but would otherwise be ignored

This is a bit of a nitpick, but can this page: https://www.mersenne.ca/userfactors/any/1/bits (and related) have an "snfs" category? Factors like those found by Joppe Bos, Thorsten Kleinjung, Arjen Lenstra, Peter Montgomery were found by SNFS, not ECM.

M991: mersenneforum.org users, see https://www.mersenneforum.org/showth...290#post404290 M1061: Greg Childers, see M1061.pdf Might also be good to give credit to finders instead of listing them as "anonymous"
