    I am looking through my results and I find that my wingman often is claiming far few credits than me.

    example
    me: 2.3GHz i5-2410M => 84 credits
    wm: 3.0GHz Core2 CPU E8400 => 47 credits

    Why is there such claimed credit differences for the same task?

    I understand that a faster computer should crunch the same amount of work in less time. But it is the same amount of work and credit should be the same.

    Is credit given out merely based on elapsed time, thus faster computers receive less credit for the same work? If so is there is no incentive for either crunchers or non-crunchers to participate in this project.

      In the project standard credit system is used. Value of credit if based on real PS's performance and on results of BOINC's benchmark. Sometimes benchmark's evaluation differs considerably from reality. It can occur, for example, if your wingman's BOINC started benchmark when OS was busy with another application.

        Thank you.
        It may in fact be my own benchmarks that may be crazy. The most recent one started at an odd time when I was doing other stuff. And this morning another project started showing the same variation.

          Oleg, thanks for pointing my attention to the benchmarking issue.
