  For a compact set $K\subset \mathbb{R}^m$, we have two indexes given under
simple parameters of the set $K$ (these parameters go back to Besicovitch and
Taylor in the late 50's). In the present paper we prove that with the exception
of a single extreme value for each index, we have the following elementary
estimate on how fast the ratio in the strong density theorem of Saks will tend
to one \[ \frac{|R\cap K|}{|R|}>1-o\bigg(\frac{1}{|\log d(R)|}\bigg) \qquad
\text{for a.e.} \ \ x\in K \ \ \text{and for} \ \ d(R)\to 0 \] (provided $x\in
R$, where $R$ is an interval in $\mathbb{R}^m$, $d$ stands for the diameter and
$|\cdot|$ is the Lebesgue measure). This work is a natural sequence of [3] and
constitutes a contribution to Problem 146 of Ulam [5, p. 245] (see also [8,
p.78]) and Erd\"{o}s' Scottish Book `Problems' [5, Chapter 4, pp. 27-33], since
it is known that no general statement can be made on how fast the density will
tend to one.
