I have been fortunate to have caught and crunched 5 WU's on my laptop with continuous Inet connectivity. I noticed that the execution times were very close in duration. 56.06 ;56.8; 60.1;58.81; 57.2 hrs. (awarded points were also close) Are the WU's a standard size or will they have WU of varying size, like other projects?

Always 48 hours simulation.

Beta's over. We're in production. My prod ARP1 work units are relatively close in runtime on a particular device, but they're not identical.

Thanks Lava, so presumably they are identical geographical coverage. I missed seeing the data upload. How many upload files per WU, and what is the total average size?

How many upload files per WU, and what is the total average size? My mean uploads range from 85-100 MB, higher than the official documentation. And work units are different geographical grid squares in sub-Saharan Africa. I don't know the official size of each grid square.

The standard deviation for the runtime of the last screen-full I have is just 4.3% of the mean. If you're interested, the SD for the granted credit is 20%, but I guess that will stabilise over time.
