Guess that question has been discussed before, however could not find that information.

I would be interested to estimate the part of compute power I'm contributing to the project. However all attempts have severe uncertainties. Taking the PPD and comparing it to the overall PPD (as published on EOC for example) has the influence of quick return bonus, as a result fast hardware will indicate to high, slow hardware to low share. Part of completed WUs probably is also misleading, as CPU WUs seem to finish much faster on my system than GPU WUs and in general the compute power requirements differ widely over the WUs. Base points per day I could not find published, furthermore I don't know statistics which show base points completed instead of PPD.

So in my case the estimate ranges from 1/5000 of compute power (200WU/d compared to a total somewhat above 1MWU/d in total) to 1/3000 (11MPPD compared to about 30GPPD in total). The PPD based calculation does not properly take into account the compute power supplied by clients without passkey.

Is there a better way of estimation?

This calculations however, even in the weaker case of 1/5000 of total power, lead to some interesting commercial considerations. If I roughly estimate my expenses for hardware in the range of EUR 7000, then the hardware value for providing the compute power of FAH is about 35M EUR. That seems quite cheap compared to supercomputers providing the same performance. That of course works only in case of workloads that can be divided in the way FAH does.
