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. Using some assumptions and approximations, 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.
