Try calculating a pressure autocorrelation time. From this, you should

be able to estimate how many independent pressure observations you made

over the course of your 10ns simulation. Using that number, you can

calculate the standard deviation of the mean pressure. If the standard

deviation of the mean is larger than the average, you don't have enough

sampling; if not, then you've got another problem.
