First come machine benchmark - it estimates how fast a particular computer is. It is done by BOINC lient.
Second comes task estimation - it comes from project server.
Those two are doing initial duration estimation and how much work will be downloaded in your cache.

The more tasks are done, the more accurate estimation comes - it is when "duration correction factor" comes.

As far as I know, there is unfortunately only one common duration correction factor for PrimeGrid, valid for all subprojects.

If your new task is of another subproject, say up to now you had sieves and the new task is SoB LLR, the duration correction will be unfitting. During progress of the task time estimation will be updated.

Which means, that the estimated runtimes are only correct after you ran some of the tasks AND the taskduration is always about the same or slowly decreasing/increasing in the long-term.
