Suppose that in the situation of Fakt. Then the generic elements are parameters. In the polynomial ring we have for parameters of degree the inclusion

because the graded Koszul resolution ends in and

So the theorem implies for a graded ring finite over that holds for generic elements. But by the graded Briançon-Skoda Theorem (see Fakt) this holds for parameters even without the generic assumption.
