Welcome home GriffTech.  Glad you finally found us.

Ask away! You might get answers to your questions, and if you're really lucky, some of them may be right .

Where did you change the 10 days?  Safest bet is to change it on the project website.  For you, I'm assuming it's seti but it works the same way in most projects. 

In your account at http://setiathome.berkeley.edu/home.php

Click on the Computing Preferences link.  Change the values to whatever you want them to be, then save them.  Then go into boinc manager on your computer and hit update.

Setting local preferences in the boinc client is iffy, I'm not sure it works 100% of the time.

For the graphs, you need to get some results granted before any of that shows up in your client program.  Y axis is in "cobblestones" (or credits as we sometimes call them) and x is time.  The X axis will start to populate when you're granted credit for the results you turn in.

Credits aren't granted immediately, there's a quorem system and I believe at least two people need to turn in valid results for a wu before they're granted any credit. 

Hope this helps.

I have all my projects configured to connect every 0.01 days (forces reporting faster) with an additional 5 days' worth work.  Seems to keep my queue loaded up and results flowing back nicely.
