1.       & Pre-evacuation time distributions   & Verif.1.1  & OK \\
2.       & Speed in a corridor                 & Verif.2.1  & OK \\
3.       & Speed on stairs                     & Verif.2.2  & OK \footnote{The method is not straightforward}\\
4.       & Movement around the corner          & Verif.2.3  & OK \\
