Without knowing how each image was processed it's hard to draw any conclusions.

Yeah, and why is the DP2-image almost as big as the DP2Q one and a lot bigger than DP3M-Image?

Because the author tried to minimize the size difference by using half size from SPP for Merrill and Quattro.

However the "half sized" Merrill image is pretty much smaller than the half sized quattro image! It's taken from a greater distance. In the result he didn't minimize much ... the Merrill image is far to small.

So I still don't get it. He took the images with varying distance and just tried half sizing? Why halfing? To avoid making resampling algorithms become more important and to make the high res sensors more comparable? Well, okay, but he should have chosen the same distance!
