Polynomial bound relating homological degree and regularity

Let AA be a standard graded algebra of dimension dd, and let hdeg(A)\operatorname{hdeg}(A) and reg(A)\operatorname{reg}(A) denote its homological degree and Castelnuovo–Mumford regularity.

Homological-degree regularity conjecture. There exists a polynomial f(t)f(t) of degree dd such that

hdeg(A)<f(reg(A)).\operatorname{hdeg}(A)<f(\operatorname{reg}(A)).

The source notes that this holds for one known homological-degree function and asks for such a polynomial bound in general; no resolution is given.
