Am I doing it wrong?
 
Okay, I was bored and was poking around and I found this on my factors found with TF:
It says I found the factor with P-1, when I actually did it with TF

31,321,219 is not very close to 3,125,237...is it possible the first WAS actually P-1?

Edit: You might consider upgrading to mfaktc 0.17 or 0.18 as well...

No, this is a long- and well- known problem with PrimeNet's results parser. It completely ignores what program reported the factor and guesses the work type based solely on the size of the factor: anything beyond the default P95 TF, which is everything that GPU272 does, is presumed to be P-1.

James is working on fixing it.

I run mfakto, not mfaktc :smile:
