Diamondback has 2 Buttons each side because it is designed for right- and lefthanders (lefthanders - right mousebuttons, righthanders - left mousebuttons).

IntelliMouse Explorer 3.0

Exactly

Ah - I don't know exactly what these benchmarks are trying to prove since they are pretty meaningless. E.g. I'm unable to exceed the "malfunction speed" on my mouse with the quickest moves (even with a 125Hz USB port polling speed!) I'm able to pull off on my mouse mat and usually I'm far away from even approaching these since I set my sensitivity in any game so that reaching the edge of my pad from a centered position completes a 180 degree turn (usually with a certain margin too). So - does it matter to me that I could move a Deathadder at light speed without it failing? Not at all...
I'm not entirely sure about the benchmarking methods either - e.g. the perfect control description is very vague and IMHO has to do as much with ergonomics and the fact if you can move your mouse in a straight line as it has with actual hardware performance. Again, I wasn't able to exceed the speed at which my mouse would become imprecise... Usually drivers also let you adjust the horizontal and vertical directions depending on what angle you're holding the mouse at.
Some virtual performance benchmarks don't take into account real-life usage of mice and the fact that ergonomics are usually far, far more important than any other things. E.g. I know that Logitech produces excellent mice but their top models are profiled in a way that just doesn't feel right in my hands and that would actually reduce my gaming performance and precision.

I deem the chart pretty much irrelevant because mice are not as easily benchmarked as stuff that actually yields measurable performance - e.g. computer internals. However, even for internal components many benchmarks are not very relevant since they can post scores like 220 FPS vs 200 FPS for graphics cards which again are pretty meaningless as any normal person will have their FPS locked at 60 or 75 depending on their monitor's refresh rate...

Again, I might cite examples from the paintball scene... i.e. my Angel One marker is able to cycle at speeds exceeding 30 times a second BUT this is completely irrelevant since even the best commonly used loaders have a hard time reaching 20 balls/sec loading speed, not to mention the fact that the rate of fire at tournaments is usually capped at 15 balls/sec. Does it stop anybody from including this piece of data in advertisement brochures and holding discussions or making benchmarks at internet forums? Hardly so... The marker even has a special "demo mode" for dry-firing at the highest cycle rate to show off and attract potential customers...

As long as my MX518 is somewhere near the top, I dont care what these benchmarks try to say

But i think its described somewhere on the page how they tested the different speeds.

My mousemat arrived!

haha cute.

Does it stick? I bought a cheap mousemat just for kicks, slides all over my shiney desk *bins*

i mean stick to the desk and not slide everywhere lol.
