Statistical methods for the extraction of a small shift in broad data distributions are examined by means of Monte Carlo simulations. This work was originally motivated by the CERN neutrino beam to Gran Sasso (CNGS) experiment for which the OPERA detector collaboration reported in a broad distribution a time shift by $\pm 7.1\,$ns despite the fact that the fluctuation of the average time is with $\pm 23.8\,$ns much larger. Although the physical result has been withdrawn, statistical methods that make such an identification in a broad distribution possible remain of interest.
