Post Season Predictions Using The Bill James Formula

The post season is underway and everyone is making their predictions. I was digging around the net the other day and found out that back in the dark ages of statistical analysis Bill James created a formula to predict post season success.

According to a post on seamheads James first put this together when I was a youthful 23 year old.

. . .(James) wrote about the system for Inside Sports magazine in 1982, then expounded on it in his 1984 Baseball Abstract. He developed the system in 1972 and it accurately predicted the World Series winner at a 68% clip for 12 years.
