I know that credits are dependant upon return of the same

Average credits is actually RECENT average credit, this is kind of
like a speedometer, the more units you return and get validated the
faster you go and the higher the RAC. This of course goes hand in hand
with the quality of the units being crunched, if you run across a
bunch of 10 minute units your credit will decrease because you are not
spending much time crunching each unit.
