The stats show the empirical variance of the data (i.e. sum (value-mean)^2 ),
whereas 169078 is the sum of uncentered squares.
Maybe the property could be renamed to "sum of squared deviations" to clarify
this distinction?
As for the sum, that was an off by one error (fixed in r14069).
Good catch :-)
bye,
Manuel
