\begin{frame}[c]{Conclusions}
{~}
	\begin{minipage}{\textwidth}
\begin{itemize}
\item Large portion of efficiency gain of \texttt{K\_Kst\_MC12TuneV2\_ProbNNk} inside the BDT can be recovered by applying a \texttt{K\_Kst\_MC12TuneV2\_ProbNNk} cut. 
\item I would still go with putting it inside the BDT, as it makes life easier.
\item See what other people working in this say.
