I have a question about the points, because I don't understand why my earned points are so low compared to my estimated PPD.

I've folded with my 280x for about 4 days with ~110k estimated PPD each day.

When I open the Advanced Control it shows on average for 1 WU/Project
Base Credit: ~15000
Estimated Credit: ~50000
Estimated PPD: ~110000
So how many points should I earn after I finished the project?

When I open the Web Control it shows that I've earned 99k points and I've folded 7 WUs so far.

I need between 10-12 hours for 1 WU.

How many coins do I earn after finishing the WU?
If I earned the estimated Credit, I would earn about ~110k PPD (similar to the estimated PPD)
But it looks like that I only get the Base Credit for each WU/Project (7 WUs*15000=105k, similar to my earned 99k points)

Is something wrong with my settings because I only earn the Base Credit or is the estimated PPD wrong calculated (because with only the base credit my estimated PPD should be ~35k instead of ~110k)?

Thanks in advance for clarification and help.
