82-0 is basically just making some kind of points, rebounds, assists, blocks, steals calculation. That's why having Wilt Chamberlain as your center and his 45/18 during the 1960's leads to all these high 70's wins lineups.
My guess is it runs some kind of algorithm where there record you get is based off how close you get to an arbitrary 100% threshold of the various stats.
Its addicting, it not particularly interesting in a basketball sense though.
