Odd result
 
I have noticed in the past that when I submit factors that have been found (trial factoring or P-1) through the manual pages, the server always says "Insufficient information for accurate CPU credit." For trial factoring, it seem to do OK assigning credit, but for P-1 it always assumes the factor was found in Stage #1 with B1=800000, even though the result that I send has the true information. Can someone explain this?

Today I had an even stranger thing happen, a P-1 factor was credited as a trial factor. Here are the lines from the results.txt file:
[code]
[Tue Dec 01 13:56:58 2009]
P-1 found a factor in stage #2, B1=605000, B2=17393750.
UID: 1997rj7/compq, M51200911 has a factor: 390126913731778984073, AID: F16547D743B533B97C9EBCA541EFDDF8
[/code]
and here is the result that came back from the server:
[code]
Factors found: 1
Processing result: M51200911 has a factor: 390126913731778984073, AID: F16547D743B533B97C9EBCA541EFDDF8
Insufficient information for accurate CPU credit.
For stats purposes, assuming factor was found by trial factoring using prime95.
CPU credit is 1.0510 GHz-days.
[/code]
What gives? :confused:

You just have to check that the computer you move the file to has communicated and thus has no .spl file of his own, then after moving the file you initiate the communication with the server or just wait for the next automatic communication. You will not need to use the "Manual Communication" pages and your results will be accepted as they are.
