Hello, I just installed BOINC climatepredition.net (CPDN) and this morning the first trickle was uploaded. I looked at my account and found the following: Total Credit: 94.52 Rec. Average Credit: 112.63 With only one PC and only one result (trickle), should they not be the same? Friedrich |

So since your trickle duration was less than a day, it adjusted it to what it would have been in a day? |

It's worth adding for the benefit of new users that RAC is not a reliable measure in CPDN anyway, as it often goes haywire after a model is completed. Credit is given on trickles returned, and is recalculated when a model is completed, but errors in RAC are not corrected. |

I finally found some information on the RAC and how it is calculated and updated. I guess I better go by Total Credits rather than RAC. Thanks for the answers! Friedrich |
