Teams with a better than .500 (or more than 50% of the available points actually) record qualify for some post season play in their respective division - so they know when they make it or not.
The 10 teams selected for the Super 8 are selected in a dark room with no windows in the basement of the MIAA HQ. Brilliant local hockey minds vote to assemble the 10 teams who make the tourny. The bottom 4 teams, 7-10 play a 'play-in game' to narrow the field to 8. The play-in losers drop down to their respective D-1 tournaments in the North of the South (and traditionally they proceed to win a game or two and flame-out never making it to The Garden).
The 8 remaining teams play best two out of three format to continue to the championship game.
For specific dates look at the lackluster MIAA website under 'hockey.'
