I think it's pretty obvious that variances in MP testing are not acceptable. If one card has 27 explosions in a run through, and another has 3 - or if one card has 30 players on screen while another has 5. What's the obvious conclusion here? I'm not sure what these guys are even arguing against, these tests NEED TO BE CONSISTENT. Period.
I really feel like it may partially be due to David having done these tests as i've never seen him do the prior tests with BF3 and what not (which seemed to have consistent results), and no disrespect to him because I'm sure he put a ton of work into it - but prior tests from what I remember were done by Brent and Grady. I think that seeing the 760 ahead of the 770 in these tests should have prevented publishing. Maybe he was caught off guard or something. I don't really know. I don't think that any errors were intentional, and the guys that are saying that are basically trolling. HardOCP has tested like this forever, so...whatever. People see what they want to see and claim "bias" when their vendor doesn't win which is really freaking stupid. IMO.
That said, the bottom line is, there is value in MP testing. I completely agree with HardOCP on this, this is how people play BF4. But, I also think that MP testing should be highly controlled perhaps with a squad of 5-10 people that do consistent actions throughout a run. Just joining a 64 player MP server and hoping for the best (and i'm not saying this is what happened, but the 760 being ahead of the 770 makes you wonder) clearly won't cut it.
Consistency and lack of variance is crucial to any type of benchmarking.
