I was always told that you mustn't quote an average to a greater precision than the accuracy of the instrument. That doesn't necessarily mean I abide by that, though... :)
It does minimise the error. I read my barometer to the nearest mb. If
I had 1,000 barometers calibrated to the same standard, and managed to
read them all at the same time, and took the mean, it would be
reasonable to quote it to a higher level of precision.
