First of all I need to tell that I am not a credit-hunter. I am here for the project as I find it very important. I will stick to the project. And when buying new PCs of graphic board I will make sure to choose nVidia. Credit shows my contribution to the project thus yes I want my credit as high as possible.

I see this 'strange' credit:

Run Time CPUsec Credit
76.706,29sec 8.204,48sec 59.500,00
75.769,23sec 7.568,39sec 71.400,00
69.190,52sec 4.798,45sec 86.850,00
67.400,43sec 20.279,36sec 64.200,00

So a job that runs faster gets more credit than a job that needs more 'power or time'? I can understand that but the difference is rather large. Is this normal?
I have looked a bit on the forum for credit questions but could not find a good answer.

Greetings from TJ

Seven scientists currently make up the GPUGrid group. There are several task types currently being run at GPUGrid, from the different scientists. Some even have more than one task type. The performance of each type of task varies, so your observations are normal. Tasks that utilize the GPU more greatly tend to award better credit. Tasks that don't utilize the GPU as well often require more work by the CPU than tasks that have high GPU utilization.
