I wonder if the Grid Server is more intelligent than I first thought? Among my devices allocated to WCG I have a laptop, a PC whose primary task is hosting a CCTV multi-camera system, several machines that are dedicated to WGC exclusively, and a PC that I use for all my "normal" computing. All my devices are permanently available to the WCG project.

I've noticed that my laptop usually gets quite short work units of just a few hours, whereas the devices that are allocated exclusively to WCG amost always get really big work units lasting several days. The other two PC's get a real mixture of work units from very short to very long. I accept that the exclusively-dedicated PC's are less powerful (73% score) than my other devices (107-120% score), but I have taken this into account when making my judgement.

Is it possible that the server deliberately allocates work units that it feels are most suited to the device in question?
