Please remind all of your supporters who do not allow CPU-calibration, that the default setting reduces credits - not just for themselves, but also for their wingmen.
CPU-calibration is the basis for many credit calculations - professor Andersen ought to stipulate that BOINC insists that hosts register CPU-calibration before they are allowed to participate in BOINC. But that is a different matter.
I trust you know what you are doing to attract followers to this exciting project.
