You can also look at the list by user and by year, and see that both LaurV and George have missed a P-1 factor.

Hmmm...I've missed 4, one recently (10 months ago); interestingly I found it myself via TF a couple months later.

Could this suggest a bug in Prime95? or more likely a hardware failure?

Early versions of Prime95 had P-1 bugs so there's lots of P-1 efforts from circa 2000-2005 that missed lots of factors.

But aside from that, there are still a (small) number of P-1 failures still occurring. I would guess that they're more hardware-failure than software-related, but I don't know enough to comment any more than that.

Huge James!

There's nothing quite like the empirical...
