DxO is over confident in (arbitraily choosen) mathematical formulas. Unfortunately.
As a photographer, I cannot trust any rating scheme which gives aggregate ratings like:
K20D: 65.4/100 (ranks #16)
GX20: 68.7/100 (ranks #10!)
(based on RAW which doesn't differ from one model to the other).
On topic:
The way DxO defines DR is
DEPENDENT on the pixel resolution (a 1 Pixel sensor would always win...). So, my advice here is to only compare cameras with identical #pixels or completly ignore the measure.
