From an analysis standpoint, it is not a problem. You'll have to decide
if it is a problem from a psychology point of view.

Hello,
I have a general design question about variation in the duration of
null intervals.
After running optseq with tnullmin set to 4 and tnullmax set to 10,
the null intervals were nearly all 4 seconds in duration, with a few
of 5 seconds. Is it generally a problem to have mostly identical null
durations throughout a scan (there are 60 trials in this particular
task)? If so, would you recommend reducing tnullmin to 2 seconds?
Thanks
