Please give/or direct to, a defonition for BS-RAC...
I believe RAC stands for 'recenty added credit'...
Is BS-RAC the sum of the recently added new credit added to the previous credit?
What is the signifigance of the graphs that show this information (or where can that info be obtained)?
And the "official" Definition of the recent average credit can be found in the
unofficial BOINC-Wiki, here is the link to the information about RAC:

So how is the Recent Average Credit computed? Each time new Credit granted, the following function is used to update the Recent Average Credit of the Computer, Participant, or Team:
RAC(new) = RAC(old)*d(t) + (1-d(t))*credit(new)
Where d(t) is the decay function, and t is the time (in seconds) since the last Recent Average Credit recalculation.
d(t) = e^(-ln(2)*t / 604800)
The Recent Average Credit for any Computer, Participant, or Team is calculated every time that Credit is added to that object. Please see also the example on the right.
Note:
Also, the Recent Average Credit number is updated when Credit is granted after the Result has passed Validation, not when a Result is returned. This is true for all current Projects with the exception of Climateprediction.net (CPDN) which has different Quorum Rules.
