I've only crunched a dozen or so WUs so far, and I can't figure out the credit granting scheme.

Looks like you might have changed to a fixed credit scheme as 27.35 seems a common value, but thats awarded for WUs ranging from 19,744 seconds to 67,079 seconds. But then there are some other random amounts of credit for shorter WUs.

My daily RAC varies from 70 to 307 across similar spec hosts, with an average of 144. For these hosts I get an average of 381 across all the other projects I crunch (all hosts are P4HT, hence the low figure).

Looks like the credit needs at least doubling to be even remotely 'fair' ;)

Another issue to fix, look at points for this WU:

One of my WU crashed without a reason (not points related problem):

Looks like the Linux Box's get better Credit than the Windows Box's & then some Box's like this one http://stat.la.asu.edu/NumberFields/results.php?hostid=172 than any of the Box's do ... :/

And then, just to prove me a liar, the last 4 WUs I returned had sensible credit ;)

Looks like the standard BOINC granting method now.

Perhaps it was the truly magically 'CreditNew' getting it's act together ;)

The credit granting does seem a little suspect. I haven't changed anything with the Boinc code, except what was necessary to get the project up and running. But I will put this on my list of things to look into. If anyone has any ideas as to what the problem could be, I am open to suggestions.

No idea here. These three tasks all from the same host, all run in sequence, all the same app version got granted wildly different credit. The lowest one was about right, the next was too much, and the highest was *way* too much (not complaining, makes up for the really mean ones!):

My only guess is that it's something to do with the widely discussed 'CreditNew' system, but I'll leave that for other to discuss :)
