Define "stale statistics".
As far as I am concerned there are two types of statistics - those that
accurately, or adequately, describe the data in the table for the
purpose of the optimizer - and those that don't. Freshly computed
statistics can easily belong to the latter category while months or
years old statistics can just as easily belong to the former.
