On my drop weight machine, it pulls and holds the desired tension. The crank varies by as much as 5 pounds, depending how fast you turn the crank. If you crank it slowly, it is within 1 to 2 pounds of the tension.
Drop weights are by far the most accurate tensioner.
The difference, I would guess, is intention. The overshooting of tension is not a desired trait, for some stringers.
