You're right, it's not.  It explains voting restrictions when
configuring qdisk, but... not *why*... e.g.:

   * Cluster node votes should be more or less equal.
   * The total number of votes assigned to the quorum device should be
     equal to or greater than the total number of node-votes in the
     cluster.  While  it is possible to assign only one (or a few) votes
     to the quorum device, the effects of doing so have not been

CMAN has no knowledge of qdisk's internal "score" information nor its
heuristics, or even how it works.  I should make a note of that.
