Let $f$ be a transcendental entire function of finite lower
order, and let $q_\nu$ be rational functions. For $0\gamma\infty\,$ let
$$
B(\gamma):=\cases{
{\displaystyle\frac{\pi\gamma}{\sin\pi\gamma}}\hbox{if }\gamma\leq 0.5,\cr
\pi\gamma\hbox{if }\gamma>0.5.\cr}
$$
We estimate the upper and lower logarithmic density of the set
$$
\Bigl\{r:\sum_{1\leq\nu\leq
k}\log^+\max_{|z|=r}|f(z)-q_\nu(z)|^{-1} B(\gamma)T(r,f)\Bigr\}.
$$
