What is wrong with you! You have some weird ideas about other people. And math. And probabilities.

K80 produces 110 GHz D/d on PRP tests. It produces 800 GHz D/d on TF.

If factoring is what you want to do, GTX 16xx, RTX 20xx and RTX 30xx are the things to get. For example, 1650 produces 800...

Doesn't make sense. WIth PFactor, the bounds are determined by the number of tests saved. If it already has a factor, then why bother? Pminus1 has exactly what you need.

Considering the fact that a) TF doesn't find composite factors (outside the bit depth), b) the factors are P-1 smooth, and c) missed another factor in the range, this is almost certainly a P-1 find.

True, but 30.8 still yields much larger ratios compared to 30.7 even at wavefront, especially if you throw something like 50GB at it. Maybe 200x-300x instead of 30x-40x?

You have not allocated sufficient RAM for P-1 stage 2. Change the setting from the default 300 MB to as much RAM as you can spare. That will cause it to do proper stage 2.

Credit calculation is done server-side. Nothing can be done on the client side. You're perhaps confusing it with improved "cost estimation" which is needed to select optimal P-1 bounds.

Probably way too low. I'm guessing B1=65M would be needed, but for safety margin, I'd go with B1=100M. Unless ... you're planning on additional TF.
