Yes, you are correct. Sorry. The math involved before hand.. finding the Pitch Radius using ES, TD &TD2 is extremely important. Forgive my over simplification of simply the thread height. But it’s still numbers in, settings made and threads come out. There’s no mysticism.. no art, right? The machine only knows to do what the user tells it. And of course it’s tolerance holding capability, right? My point was a slightly tighter/loser nut doesn’t add to accuracy potential. (And I’m speaking about bore/thread cutting squareness) But the actual “play”, only matters to the clamping torque, right?

I think Fuj’ had a bad specimen. It happens. I’ve had two of these & they don’t rock when threaded on. But they aren’t as tight as other nuts I’ve felt.
