  Using traditional Virasoro $L_0$ level-truncation computations, we evaluate
the open bosonic string field theory action up to level $(10,30)$. Extremizing
this level-truncated potential, we construct a numerical solution for tachyon
condensation in Schnabl gauge. We find that the energy associated to the
numerical solution overshoots the expected value $-1$ at level $L=6$.
Extrapolating the level-truncation data for $L\leq 10$ to estimate the vacuum
energies for $L > 10$, we predict that the energy reaches a minimum value at $L
\sim 12$, and then turns back to approach $-1$ asymptotically as $L \rightarrow
\infty$. Furthermore, we analyze the tachyon vacuum expectation value (vev),
for which by extrapolating its corresponding level-truncation data, we predict
that the tachyon vev reaches a minimum value at $L \sim 26$, and then turns
back to approach the expected analytical result as $L \rightarrow \infty$.
