Are Quad ratings determined at the end of the season and then retroactively applied to all teams/games over the course of a season, or are they locked in place at the time the games were played? For example, we beat Purdue when they were a Quad 1, but let's say they finish the season poorly and end up as a Quad 2. Is that a Quad 1 or Quad 2 win for us? TIA.
