I think FAHSPY might be showing a more realistic number.
I was always a little skeptical about the FAHMON displayed PPD.
I check my stats at EOC often and have found Fahspy fairly accurate, minus the downtime between units of course. It's just a matter of personel preference...
Install GPU2 - make sure you know the path to the Work folder.
D/L Fahmon
Install
Run
Right click the window, clock Add new client.
Add a name for the client
Browse to the Top folder where the Work folder is situated - not the actual Work folder.
It may take a few percentages until Fahmon recongnizes the Client.
You can add as many as you wish, even over a network (just like I did).
That works for me; I'm using Fahmon, with Vista Ultimate 32bit.
Here is one question that I always wondered: will closing down my system mean that I loose all of my work done to that time if I haven't finished a WU with the GPU2 client?
