Both cameras have the same pixel size and bits per pixels, so the buckets aren't 5 and 10 litres, they're both the same. I wasn't arguing about the total light captured, but the total captured per mm, or per bucket. The same amount of water will be captured in the center buckets in each case, as they're the same size and depth. That's what makes me right.
Due the the extra buckets, you can downsample, and get the effect of less noise (Daniel had a whole big thread all about it), but at the original capture size, the noise is identical at the pixel level. Or due to the extra resolution, when printed, any noise will be rendered smaller, and thus less visible. That makes you (and DxO) right.
