claimed vs. granted credit for different projects

Hello,

I'm Einstein and Seti "cruncher".

For Seti claimed vs. granted credit is approx.
3,56 vs. 3,50 credit/ms

For Einstein claimed vs. granted credit is approx.
3,51 vs. 2,64 credit/ms

So although I currently prefer crunching for Einstein,
it seems that I get approx. 25% less credit granted
than for seti.

Anybody out there with same results ?
Or anybody with an idea that brings more
"democracy" to the different projects ?
Or is there any other reason for this effect ?

Best regards
Markus
