downsize the D4/D800 results to 12MP?

It may be something similar to this: IIRC D800 is 36MP? Then going to 12MP would be like an increase of 10 x log10(36/12) = 10 x log10 (3) = 4.8 db. I think if you compare the D800 native graph (red) with downsized graph (green) then just eyeballing, the difference is about ~5db (~4.8 db).

Sincerely,
