My data on number PRP/LL tests (especially as it relates to whether an exponent is considered cleared or not) is incomplete at best.
I could potentially make use of the data here...

I don't know when PrimeNet's TF thresholds were updated (probably browsing through source code commonc.h for recent versions of Prime95 would reveal the change version/date). The threshold numbers I...

This is why we need more dedicated P-1'ers at the wavefront.

Pfactor=1,2,859433,-1,0,10 was what I used for the above. (I came across this exponent on my "worst P-1" page, before I excluded prime exponents, and it had the erroneous TF=0 level). Perhaps Prime95...

It seems that the P-1 probability algorithm breaks down somewhat when presented with extreme cases of exponent size, bounds, TF. I have fixed the 3 specific cases you listed, and if any other cases...

This is normal. When a composite factor is found, it is split into prime factors (which could take several seconds to process) and each prime factor is inserted into the database. An unfortunate...

I have attached the PHP code that contains most of the lookup tables and credit formulas.

I'll look into that and make them available in the near future.

Neither has M1277 (https://www.mersenne.ca/exponent/1277), but as kriesel said, less of (71|target). I was mostly talking about exponents in the 1000M-4294M range, but it looks like all exponents 9M...

Correct. I believe everything in the 1G-4G range has been exhaustively TF'd to 64 regardless of factors found, and all exponents either have known factor(s) or have been TF'd to 71+

Maybe you could post the assignment line (with the assignment ID masked or replaced with N/A) so that George (or whomever) can easily test the same thing you're running.
