This is a 'scorecard' by conference for 2004, the 6-th for the 64-team playoff system where every conference gets an automatic bid. You can find the full results elsewhere.
My original motivation for this summary was the thought that the regionals are a major source of inter-conference and inter-region play that helps one evaluate the relative strength and (possibly) future seedings of teams from various regions and conferences.
Current status: Super Regionals are complete.
Here is the 'histogram' of the success rate for the 2004 NCAA regionals.
I tally a Regional champion under "win" and the Super-Regional champion (the team that goes to the CWS) under "champ" so the "champ" column is unchanged from the older 48-team system.
