  We investigate performance of approximations put forth in
\citeNP{[Malinovskii 2017a]} and \citeNP{[Malinovskii 2017b]} for the
distribution of the time of first level $u$ crossing by the random process
$\homV{s}-cs$, $s>0$, where $\homV{s}$ is compound renewal process. In the case
of Exponential inter-renewal and jump size random variables, we compare the
approximations with exact and with simulation results. In a few other cases
including Erlang and Pareto inter-renewal and jump size random variables, where
exact results are absent, we compare the approximations with simulation
results.
