I thought I understood the credit algorithm ... multiple clients perform the same piece of work and all request credit for that work. The results are sent in and the credit given to each client is the lowest credit requested.

But then I saw this result:

And I guess I am not sure anymore.

Looks like the median credit was granted.

You shouldn\'t count Result#3315939, the credit was already \"decided\" by the time that one arrived (since quorum is 3).

And why do you sometimes get no credit having a correct result?

Seems to be a problem on linux hosts. I have got the same problem on my linux host. Results are marked as invalid.

Maybe they failed validation?

You\'re right. But why do they fail so often? The problem could be that i\'m using the amd64-client which requests 64-bit project files that could be unstable.
