Average days to detection at 1 false positive per month for "medium-sized" outbreaks injected into each dataset, using empirically determined thresholds on p-value (computed by randomization testing, using empirical/asymptotic p-values [37]) and score (without randomization testing) respectively. If there is a significant difference between the detection times with and without randomization, the better-performing method is marked in bold.
