The issue isn't with the extreme results though, yeah it's up to a bencher to check their scores against others, and if they see they're beating people with far higher clocks etc, then something might be up. That's not the issue though, it's the small gaps, where there might be some artifacting but nothing crazy, and so your score is slightly better than someone at the same clocks as you, who are you to know (especially as a novice in 3D) that your score is bugged rather than you happened to find a good series of settings etc that got you that extra 1%?
I completely agree with you on the big stuff, but it's the rest I'm concerned about.
