It is my understanding that a PRP test can show one of:

Unverified (suspect) -- single test but errors were detected in the test
Unverified (reliable) -- single test and no errors detected
Verified -- PRP confirmed either with multiple tests or proof, no known factors
Verified (factored) -- PRP confirmed either with multiple tests or proof, some known factors

PRP tests are always run on the smallest unknown, in most cases that's the entire Mersenne number but when factors are know then it's the remaining cofactor, which is also usually composite but occasionally (as here) you find a large PRP cofactor that is usually (always?) eventually certified-prime.

Ah, that explains why these results are marked as "factored." However, this is inconsistent with regular primality test results, which are only marked as "factored" if a factor was actually found.

If I remember correctly, PRP cofactor tests worked the same way until recently. I feel this could be confusing because "factored" implies that further factors were found since the test. For example, the cofactor of 10010081 is marked as "factored" even though the exponent has only one known prime factor. The label would imply there are at least two.

Perhaps other members could chime in.

59059697 shows the result turned in yesterday by Anonymous. Are you sure that your machine is set-up to be connected to your PrimeNet account (not your forum account)?
And 63159671 is assigned to Anonymous too.

And don't post assignment IDs.

Thank you for removing the assignment ID.

This CPU has already delivered a few results under my name, and its status on the page was green, so I (wrongly) assumed it is connected.
It hasn't been used for a while and lost the connection to my PrimeNet account.
I set the account again, and it is ok now. Thanks for the hint!

What is interesting though, my computer was given GHz Days for this one, but my PrimeNet account was not.
So, my PrimeNet account's GHz Days is no longer the sum of all my computers' GHz Days.

George or James can fix this for you, and assign you the proper credit if the report came from the same system (which is easy to check).

Is the DB corrupted?

This problem still exists. It has expanded into other parts of the DB.

Adding the assigned and available 3302 + 32 != 3338

Not sure if it's worth mentioning here, but I seem to be able to manually submit my small ECM'ed assignments multiple times and I get credit multiple times for only one iteration of the for example 7 curves I ran. These were assignments I received through Prime95. I decided to submit my Prime95 results file manually due to having ran some unassigned work on small exponents. I'm not sure if me having sent multiple ECM results (that were essentially the same work done) has in some way added on to a tally of these curves being ran on those numbers.
