What this means is that the quorum is preserved if (and only if) the sum weight of the nodes in a new component strictly exceeds half that of the preceding :term:`Primary Component`, minus the nodes which left gracefully.
What this means is that the quorum is preserved if (and only if) the sum weight of the nodes in a new component exceeds or is equal to half that of the preceding :term:`Primary Component`, minus the nodes which left gracefully.

You can customize node weight using the :ref:`pc.weight <pc.weight>` parameter. By default, node weight is ``1``, which translates to the traditional node count behavior.
