Bill is right on the money. Hahnemule's recommendations for media settings in above link, are not accurate and are not necessarily the best choice. These are the ink limits for some of Hahnemuhle papers. These numbers are provided in data sheets by Hahnemule for all of their media:
Ink limits for PR Baryta, FA Baryta, PR Pearl, FA Pearl : 280
Ink limits for PR Satin : 235
For 3100, Hahnemuhle recommends FA Pearl-less ink for all above papers.
If you check the ink limit for their Matte papers , you will find the same inaccuracy for paper setting.
The ink limit for most of their Matte papers 245, with these exceptions:
Bamboo : 235, Natural art Duo : 250, PR ultra smooth 280.
Although the above papers have different ink limit and thickness, They have recommended Fine Art paper >250 for all the above.
Their recommendation for media setting for Z-3200 is not a help either and looks more like a joke! For every single paper, the setting is "Import as new media to the printer"!!
Not tried PR Baryta myself , so don't have the proper answer, but it will worth to try some other settings with a bit higher ink limit.
