The purpose of the present paper is to systematically assess the distribution of properties obtained in long-timescale simulations. By performing ensembles of 10 to 12 ten-microsecond unbiased simulations, we are able to evaluate the utility of running individual long-timescale simulations, investigate their reproducibility and compare the results obtained from them to an "adaptive-sampling" scheme which consists of 9 microseconds of aggregate simulation time. This is of interest as the wall time required to execute the long-timescale runs is significantly longer than the wall time required for the entire adaptive sampling protocol (differences are on the order of weeks).
