The Passer Rating is calculated using each quarterback's completion percentage, passing yardage, touchdowns and interceptions . The current "passer rating" or "quarterback rating" system (the former term being the official one) was conceived by Pro Football Hall of Fame's Don Smith in 1973; it was then applied retroactively to all previous seasons. The system is of a sliding-scale design, where outstanding performances meet diminishing returns faster than sub-par ones. The best passer rating that a quarterback can obtain under it is 158.3 (technically 158.333→), while the worst is zero. Conceptually, the average rating would be 79.2 (technically 79.166→), since this is equidistant between zero and 158.3, but the architects of the rating had 66.66→ in mind as the "average" score (100 * /6). The cumulative league-wide average passer rating for the years 2000 through 2003, all inclusive, was 78.9 (the figure is typically rounded to the nearest 1/10 of a point); however in 2004 the league average was 82.8, the highest ever recorded. This may be due, at least in part, to stricter rules regarding pass interference.
