Curious: I have an Encore and I still get a bit of fine sludge. I'm grinding on about 21. What setting are you using?

I personally have it around 32-33. I don't remember if I got that from their manual or from somewhere online, but I haven't noticed any degradation in flavor from the larger grind. The whole point of investing in a quality burr grinder is being able to get a proper coarse grind; make use of it!
EDIT: A separate Reddit post (though by no means authoritative) agrees with my recommendation of above 30 for FP:

I've only been using the french press more now because my home office is upstairs, and the Clever Dripper stays in the kitchen. With the press I can bring it up with me and save 4 whole minutes in my 'commute' :-)
