But on topic:
I don't have any objections about a credit deviation of about +/- 10%, but the use of the so-called "optimized" clients, that do nothing but fiddle with the benchmarks, is something completely different. They do nothing for the science, they only claim more credit than usual.
The admin of RCN stated it quite correct
in his forum, and that's why I restarted my crunching over there.
About 5 percent of our participants use "optimized" clients. They should know that these clients don't do more work. They just claim more credits. And this is not fair to other users! This is cheating and it harms the project.
However I decided only for moderate measures that clip off credits for the machines that claim to be 3-40 times faster than our fastest machine. I know that this is not a perfect solution but I'm no credit sheriff and no nursery teacher. I have enough to do to keep the project running and this server isn't even part of my job.

If you have compiled an optimized science application, and use the "optimized" client for the compensation of the loss of credits/h through the original BOINC method of claiming, it's imho OK, but that's the exeption to the rule.
As BOINC is open source, and I want it to stay this way, perhaps it really is the best to put the credit stuff in the science app (if closed source) or entirely on the server. Unfortunately this is not always possible, so the quorum is another good method of restricting the abuse of "optimized" clients. As you can see, it's even posiible in projects with a quorum of 1, if the WUs are comparable enough, like it's done @Rosetta since today.
