I have send back several wu´s, but all credits are still pending and not granted yet. What is the problem?

It takes 3 computers to crunch a work unit. Only after all 3 computers have sent back their data on the unit and the claimed credit is validated, do you get the middle amount of the claimed credits.

This means that if you ask for 23 credits, a next computer asks for 72 and a third asks for 55, then you all get 55 granted credits.

Thanks for the answer. I would like to point out that this is contary to what is written on http://boinc.ssl.berkeley.edu/intro_user.php:

When at least two results have been returned, the server compares them. If the results agree, then users are granted the smaller of the claimed credits.

No wonder I was a bit puzzled when I had sent back a work unit, and saw that a second user had also sent back the same work unit, but my credits were still pending.

I agree with the confusion. It also says the same thing on http://boinc.berkeley.edu/intro_user.php#credit (which is the official Getting Started link).

But they changed the checking between 3 clients and taking the middle amount on the Beta servers, so we can easily assume they are using the same form of checking here. :)

It was actually changed on this project first IIRC.
