One more thing that should be noted: not only do you have to repeat testing over and over again, which takes a lot of time, you also need to actually have the processors at each speed grade.
Life was a lot easier when multipliers were unlocked and you could just simulate certain processors with underclocking and such... but it's significantly more difficult now.
Hell, give me Anand's lab and a salary and I'd be happy to do it, though
As for stuff I hate, graphs that don't start at 0. Agh, it pissed me off to no end.
