This is a 'scorecard' by conference for 2017, the 19-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 selection or seedings of teams from various regions and conferences. I think it still serves that purpose.
Current status:
Regionals complete. Super Regionals in progress.
Updates will be slow this year.
Here is the 'histogram' of the success rate for the 2017 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.
Note:
There are no changes in the conference lineup this year, which still has 31 conferences,
all with automatic bids (so 31 of 64 are automatic qualifiers).
One notable change is that Maryland left the ACC for the Big Ten, which has 13 of its 14
teams playing baseball and is now competitive on the national stage.
