A comparison is made between \(c\)-density and \(k\)-density in the general setting of Freedman density spaces [\textit{A. R. Freedman}, J. Reine Angew. Math. 235, 1--19 (1969; Zbl 0211.38301)]. In particular, there exists a fixed density space such that for any two real numbers \(\rho_1\) and \(\rho_2\) with \(0\leq \rho_1\leq \rho_2 < 1\), a set can be constructed having a \(k\)-density of \(\rho_1\) and a \(c\)-density of \(\rho_2\).
