How is this worked out? Is it an average of all your machines? It's just that I run Folding@Home 24/7 at 100% on all my active machines and yet I'm not in the Top 10
Yea, I noticed the same too. I think that for hitting the achievement any one machine can do, but then for the overall it's something like the average of all machines.
I have my only rig running at 100% and one Virtual Machine running as "real" (VMWare 2.0x 64bit is not yet correctly identified) but the VM's cpu usage is next to none so it shows me as 70% CPU usage.
Maybe in the next version of the app my VM is able to be identified, the VM is taken out of the equation, and I jump close to the 99% folks.
