Cropping in the GFX 100RF and the effects on dynamic range

Fuji is recommending cropping as a method to ameliorate the limitations of a fixed lens in the GFX 100RF. That will affect dynamic range. I’ve calculated that, using Bill Claff’s Photographic Dynamic Range measurements from the GFX 100S II.

Here it is:

The vertical axis is PDR in stops. The horizontal axis is ISO setting. The equivalent focal length for a 33x44mm sensor is shown for each line.
