DxO measurements seem fishy

here's the plot of the dynamic range of RX100 from DxO


you can clearly see it keep on going up until ISO80

now here's quote from the Dpreview review of the RX100:

The RX100 has two ISO settings below its native 'base' ISO of 125 and, as you would expect, these both result in lower highlight dynamic range (since they are effectively the same as ISO 125 but with greater exposure). *

Along with the page where they clearly show that ISO80 has less dynamic range than ISO125


That is suspicious to me

What is worse, is the DxO graph is starting to level out as it goes from ISO400 to ISO200 to ISO100, then magically get steeper from ISO100 to ISO80. Something is clearly wrong with the DxO measurements if the base is greater than 80.
