Why am I showing up twice in the detailed stats? 2nd and 40 something for Australia?

This might be either a CPID split, or someone with the same username.
Btw.: I don't find your PrimeGrid contribution through username search, if you're the vaughan who goes through PG tasks left and right.

Yes Jens, that is me.

Ok, then you should happen to have a CPID split.
BOINC lost track of some projects belonging to the same CPID as the others and handed out a second one (or even more, in some cases).
This can happen by changing your e-mail address, or it can happen just anyway.
Usually you can get those projects to find each other back when crunching all of them on at least one machine.
But, I don't like the fact that all that I can see when I click your username is retired projects, as you can't crunch for them anymore.
This is not a Boincstats problem, it's a BOINC one.
Willy might be able to do something about this once you gathered all that can be gathered again in one place, but maybe he can't.
At Rechenkraft.net we had the same thing with our team account and fixed it by mainly crunching all active projects in atwo-threaded VM. Just some time, but it worked.
So, fingers crossed you can get it to work as well. :-)

I have tried that many times in the past to no avail. I just have to live with the fact that BOINC is stupid.
