Iím having a bit of trouble interpreting / understanding the shadow improvement chart for the X2D. My understanding is that all the values are relative to the base ISO of the camera. E.g. for the X1D, the improvement at base ISO 100 is 0, because thatís basically comparing it to itself.

https://www.photonstophotos.net/Charts/PDR_Shadow.htm

But for the X2D chart, there is no ď0Ē. Even at ISO 64, which should be the lowest native ISO, it has a reading of 0.52 stops. At ISO 100, itís 0.33. So what the the ISO value to which 64 and 100 are being compared?
