Is it our system that is going to work differently? Because BOINC says https://boinc.berkeley.edu/wiki/Computation_credit "Recent average credit: The average number of Cobblestones per day granted recently. This average decreases by a factor of two every week." And the only other discussions I've seen on line about BOINC compute it the same way. So it that document out of date, am I misunderstanding what it says or is our system utilizing a different factor?

Your not evaluating the formula exponentially and the definition is correct. A factor of two every week is the same as the RAC being fulfilled 90% within 2 weeks (its half life) and 99% in 4 weeks. Ill put the formula in biblepay so you can type exec racformula and see the RAC per day.

Mike: The formula you posted is correct- its done within the boinc network.
