I just received (yesterday) a Norton 4K stone which proudly wore a "Made In Italy" sticker which surprised me. I used the DMT325 to lap the hone. I was very happy to see that it did not take much work at all. I marked the stone with a pencil, lapped it under running water. Once the pencil marks were gone, I did it again. I would say it took no more than five minutes. Now, the Naniwa SS hones I also received took much more work. I lapped the 3K and 5K in about an hour and am still working on the 8K.
Just my 2 cents.“Two things are infinite: the universe and human stupidity; and I'm not sure about the universe.”

I have never recieved a stone that was flat.
I have found that the first lap, done on a granite lapping plate with 220 grit Wet or Dry will take off that material fast, then I can take it to my DMT D8C and finish flattening. Do the checkerboard pattern with pencil and finish it on 1000 grit Wet or Dry to finish the surface.
That's what I do...
BTW I have Granite Flattening Slabs for sale on EBay for this very process.
I never freak if they are not flat. (Not like I have THAT many hones, probably around 25 or so now) Not a single one of them was perfectly flat when I recieved it.
My 2 cents!!!!
Mike-- Any day I get out of bed, and the first thing out of my mouth is not a groan, that's going to be a good day --
