Fuji X-Pro1 - ISO 6400 - Iridient Developer

I saw in a Fuji forum the view that Iridient Developer works well on low ISO shots but not high ISO. I dug out an X-Pro1 file shot at ISO 6400 and processed it using the basic settings. Below is a 100% enlargement of a section and in common with the rest of my experiences with this software I'm once again impressed.
