  A set of equations representing the $W/Z$ mass ratio and various observables
of $Z$ decays in terms of $\bar\alpha \equiv\alpha (m_Z)$, $G_{\mu}$, $m_Z$,
$m_t$, $m_H$, $\bar\alpha_{s} \equiv\alpha_{s} (m_Z)$, $m_b$ and $m_\tau$ (all
other fermion masses being neglected) are compared with the latest data of the
four LEP detectors, which at the level of one standard deviation coincide with
their Born values. Our global fit gives: $m_t = 161^{+ 15 +16}_{-16 -22}
\bar\alpha_{s} = 0.119 \pm 0.006 \pm 0.002$, where the central values
correspond to $m_H = 300$ GeV, the first errors are statistical and the second
ones represent shifts of the central values corresponding to $m_H = 1000$
GeV($+$) and 60 GeV($-$). The predicted mass of the top is smaller than in the
recent fits by 4 GeV. The {\it predicted} values of $m_W/m_Z$ and the LEP
observables, based on the fitted values of $m_t$ and $\bar{\alpha}_s$, show a
weak dependence on $m_H$ and differ by several {\it predicted} standard
deviations from the corresponding Born values. The uncertainties of the
predicted values and their deviations from the corresponding Born values
determine the experimental accuracy required to observe electroweak radiative
corrections.
