That's one of the primary goals of the system -- when external modules
plug in their own calculations (median score, number of votes cast for a
criteria, karma-weighted vote value, whatever) the aggregate data is
stored as a 'voting result' record. Those result records are what get
queried when nodes are viewed, etc.

There's a recalculation hit whenever someone *casts* a vote, but never
when someone *views* voting results.
