So you are using the DXO data to compute some "efficiency factor" that you define yourself to draw conclusions about noise, which was your starting point to begin with? Do you understand how ridiculous is that?

Sensorgen do very interesting analysis because they compute factors which are not in the DXO data, like well capacity and read noise in e-. Those two parameters have a clear meaning unlike your "efficiency" one.

You misinterpreted my remark about the resolution of the system. Given the same noise curve, a system with better resolution has some advantage. You can apply some NR and have a lower noise and the same resolution as a lower res system.
