About Peak Career Slice
Players are created using the best 35-100% of their career. The longer the career the smaller the percentage used. Each season or portion of a season used is normalized for their home park for that season. Outlier seasons are adjusted to lesson their impact. All players are then assigned to a neutral home park and a year based on a weighted usage of the seasons included in the career slice. In an effort to remove significant outlier years the year listed for each player does not always represent the best year of his career. Ratings and statistics are based on official Dave Koch Sports season files from 1880 to present.
