Olympus 12-40 easily beats the Canon 17-55 at f/2.8 (but not when stopped down).

Because 43 gives you more resolution

I cannot say what lens rental did, but it appears that they use different methodology to everyone else. They seem to measure the resolving power of the lens rather than resolving power of lens with a sensor. I say this because if you look at their data, it appears many good m43 lenses out resolve many good FF lenses across their test. We know that simply isnt possible.

Not only is this "possible" it's most likely. Resolution is determined by pixel pitch and 43/m43 cameras generally (always?) have a lower pixel pitch. The E-M1 with an Oly 300mm f/2.8 lens has more resolution than my 1Dx with the Canon 300mm f/2.8 lens.

I'm confused why you think this is impossible.
