Dont give up, I know how easy it is to get caught up in the race for credit, but remember you started crunching seti for a reason, and Im guessing that reason still exists.
I used to crunch seti 100% and was trying to wring every last ppd I could. Then I realised that no matter what I did, I couldn't match toxic, grimgoth or halz so I stopped trying. Now I crunch seti on the gpu's and split my cpu's between MW@home, einstein, rosetta and lhc (if I can get any work)
on some of them Im averaging 200ppd, hardly earth shattering, but who cares, every little helps, and that is what counts in the end..
