The additional events from the Higgs-strahlung process at 350 GeV allow the statistical precision for all the aforementioned measurements to be improved by typically 5\% for TLEP with respect to the sole 240 GeV data. The large number of Higgs bosons produced by boson fusion allows a measurement of the total width in the ${\rm b\bar b}\nu\bar\nu$ final state. At $\sqrt{s}=350$~GeV, both the Higgs-strahlung process (when the Z decays to a neutrino pair) and the WW fusion contribute to this final state with a similar cross section (Fig.~\ref{fig:HiggsCross}). The mass recoiling against the ${\rm b \bar b}$ system (also called missing mass), however, peaks at $m_{\rm Z}$ for the Higgs-strahlung and clusters around $\sqrt{s}-m_{\rm H}$ for the WW fusion. A fit of the HZ and WW fusion contributions to the distribution of this missing mass, shown in Fig.~\ref{fig:MissingMass} from Ref.~\cite{cite:durig}, allows  $\sigma_{{\rm WW \to H}} \times {\rm BR(H \to b\bar b)}$ to be obtained with a relative precision of 0.6\% at TLEP.
