The Boinc-manager tells me, that the "duration time" (dont know the exact name) for the WUs is about 1:14h. In reality they take about 3:20h.
The value doesn't change any second when i upload the finished WUs.
How can i change or reset this value?

The problem is: i get 3x as much WUs from the server and universe often runs in panic mode (high priority), so other projects don't get much computing time.

Changing the parameter "duration_correction_factor" in the client_state.xml doesn't have any influence.
