I apologize if this has been authoritatively answered before, I've done some searching but was unable to find a previous post. I'm wondering, how are Folding@home's FLOPS calculated? Here's the information I have so far:
1. On the PS3 FAQ, there's a section titled "How are the FLOPS calculated?" but while there's useful information provided, the question isn't directly answered.
2. In July of 2011, Bruce wrote here: "I'm not certain, but I think each WU completed reports that a specific number of FLOPs were completed." I think I've read this elsewhere, and that the server measures how long the WU takes to complete, but I haven't been able to find where I read it. Has this been definitively stated one way or another?
3. I understand that FLOPS aren't the most accurate way of measuring scientific throughput. I've read this a number of times now, including in Bruce's above statement. I'm just wondering how F@h arrives at their numbers is all.
4. The native FLOPS are calculated conservatively, while the x86 FLOPS are less so. The latter measurement provides a more realistic number when considering the standard x86 hardware.
5. The FLOPS FAQ has some good information, but doesn't explain how FLOPS are measured, or if they are determined in accordance to Bruce's post.
I'd appreciate any help in answering this question. If there's any relevant posts or if the question has been answered before, I'd sure appreciate a link. I've been trying to find one.

Re: How are F@h's FLOPS calculated?
The FAQs are the published standard. Even the Client Stats page refers people back to the FLOPs FAQ for answers.
x86 FLOPs info is cited there.
PG posted somewhere that native FLOPS are tracked internally in the fahcore (gromacs code). I'd like to be more helpful, but I'm not a personal research assistant.

Actually, just so you don't waste time on this, because FLOP counts don't mean anything...

Re: How are F@h's FLOPS calculated?
7im, thanks for those links. I understand that your doing what you can, and I appreciate it. I'm just hoping someone has some insight they could share, or like you did, knows where to find some information. I realize there are drawbacks to FLOP measurements, but I'm still pursuing the topic, thank you.
F@h is now the top computing platform on the planet and nothing unites people like a dedicated fight against a common enemy. This virus affects all of us. Lets end it together.

I'm not doing what I can, but I am doing what I can to help you. People have jumped my stuff because they think I'm being overly harsh on you. They can't see that I'm actually doing you a favor. You'll learn more doing the research yourself. Like how to narrow your forum searches to find what you want, and that not everything is located in the forum or fah web site. (fah wiki, gromacs.org, News blog, etc.)

Re: How are F@h's FLOPS calculated?
Oh I see. I guess I misinterpreted your post. I've been using Google, etc. Care to provide any tips or am I supposed to wing it entirely?
