I have no idea why DXOMark is not giving the details of their test.
At least it should state its all done on standard mode (on full resolution). What focal length on the lens was set for the test etc.
I would also like to see the rating under all the three fields, colors, ISO and DR when image output is set to Medium RAW and EXR is set to DR priority.
This is a different kind of sensor and should be treated differently.
Opinion on the Score:
Even in that standard mode it is quite a decent score, considering the flexible focal range 15x and starting at 24mm.
