You've got 75,189.03seconds 219.23oc 287.22new credit 13.75189971 new credits/hour.
test it after a week, so you have a larger number of results to average.

Take a look at some of the graphs of granted credit and you'll see why we now need a fair sized group of WUs to average.



Yeah, I now see that I've received many more credits for the same times for certain WUs. Thanks!

On an unrelated note, I got a bunch of failed WUs too; I don't think I changed anything to do that...anyone else seeing that?
[EDIT]: Just received some new WUs that appear to be running fine.

I hope I'm in the right thread, please excuse me if not.

Just by observation, on my Core 2 Duo (brandy new), I'm getting less than 1/3 the credit per hour of CPU time that I receive from SETI. I am running an optimized SETI client, so that explains part of it, but there seems to be some disparity there. I'm not complaining, as I have decided to join Rosetta for the science, but it doesn't seem like it's quite on par with SETI in terms of credit.

SETI: 67 credits for 7,400 seconds' CPU time = 33 credits per hour per core
Rosetta: ~30 credits for 10,700 seconds' CPU time = 10 credits per hour per core

Basically, it seems that the new system of credit might be a bit too "coarse" from my understanding of how it works. I'm going to cut back my CPU time to a target of 2 hours and see if that makes any difference. Perhaps since I have an, umm, above average CPU, I should shoot for shorter time targets. I will post back when I have a few 2 hour WUs returned.
