Since you are talking about frames done it seems to me that you are using the graphical or regular command line client (the command line client is slightly faster.
You really should upgrade to the SMP client. You will get an average of 400-850 PPD on that client as opposed to 250-300 PPD with 2 of the regular client (since you have 2 cores).
As for the list of teams that you have donated to, there may be more than one person using your name. You may want to check if your name is unique on the folding system, I would not be suprised if it was not as they have 732,583 users in the system. My user name for folding is Aragorn1024.
Thanks for helping the team and the cause. Glad to have you with us, I hope I have been of some help.
P.S. Everyone who has 2 or more cores in their system should be using the SMP client. (Virtual cores from HT{Hyper Threaded} processors don't count. They will be very slow.)
