    Statistics are an instance of
    :class:`~robot.model.statistics.Statistics` that is created based
    on the contained ``suite`` and possible
    :func:`configuration <configure>`.
    Statistics are created every time this property is accessed. Saving
    them to a variable is thus often a good idea to avoid re-creating
    them unnecessarily::
