Two of my latest Atlas tasks (single core) were awarded only about a tenth of the credit they used to get. About 9 hours of crunching and 33 credits: https://lhcathome.cern.ch/lhcathome/result.php?resultid=130577382. They used to be like this: https://lhcathome.cern.ch/lhcathome/result.php?resultid=129619116

I know credit isn't the most important thing but why such a big change? Is this the CreditNew in action or what?

Yes, I noticed the same thing on my iMac running multicore with the latest Boinc and the latest MacOS.

There is no fluctuation - there is only one direction ==> down

For my latest ATLAS-task crunching 10 CPU hours 38.82 credits were granted:

130989742 63127816 1 Apr 2017, 6:55:39 UTC 1 Apr 2017, 12:14:48 UTC Completed and validated 19,051.51 36,224.95 38.82

They look normal on the host details page:
    Measured floating point speed 4067.77 million ops/sec
    Measured integer speed 11060.9 million ops/sec

I also see very low credit... for CMS tasks i get 5x higher credit for same CPU time.. likes as Atlas gives credit for runtime not for CPU time...
