I had a look at your stats and our stats and see the difference in volume.
Although your output is low, the chart pattern matches the chart pattern on our stats.
Thus we are subject to the same work unit availability as your team. (that is to say: the issue is systemic)
I know that we have quite a few active members with multiple computers on that project which are on 24/7, as most of us do.

Often if there is a client update on a (any DC) project we would re-install the client from scratch to make sure a problem is reproducible / complete a necessary upgrade.
However, I checked the client versions and there have been no significant changes since since 2010.

Since the issue of work availability appears to be systemic, I suspect the main difference is here is one of sheer numbers.
That is to say we have many more members running project clients than your team.

In the mean time, if you think there is a real problem, I'd contact the project administrator via their contact page: http://www.superdonate.org/contact/

However, I defer to our project leader, NeoGen, to provide further comment and knowledge as he knows this project better than the rest of us.
