Personally I prefer to use 'dmUBLOCK(-X)' for stimuli with varying durations, where X is the duration at which the response magnitude is desired to be interpreted. In other words, I would choose X so that the durations of all the stimuli are centered around X across *all* subjects. In doing so, it would simplify the group analysis as well because I would not worry about the variability of duration across subjects at the group level.
