I’ve used dough sheeters on doughs that were approaching 70% but not 75% (that’s Focaccia country), even then I had to use a LOT of dusting flour and you really couldn’t sheet the dough in the truest sense as the sheeting rolls were very wide and far apart, also the dough will be difficult to handle coming off of the slide, best part though is experienced when you didn’t use enough dusting flour on the dough and it sticks to one of the rollers, then smears around it and jams up on/under the scraper blade. A dough like that is really pretty pliable, why would you want to use a sheeter/dough roller on it? If uniformity is what you are seeking a rolling pin or pastry pin would actually work a lot better and is just as fast.
