I think you are making a mountain out of a molehill, frankly. These 
stats are not intended as anything other than a pretty indication of the 
shape, to see if they are significantly influenced by outliers. For any 
significantly large sample size the difference will be negligible.

But I will add a note to the documentation, that seems reasonable.
