Winning percentage

In sports, a winning percentage or Copeland score is the fraction of games or matches a team or individual has won.

Winning percentage is one way to compare the record of two teams; however, another standard method most frequently used in baseball and professional basketball standings is games behind.

In this case, the formula is wins divided by total number of matches; draws are not considered as "half-wins", and the quotient is always in percentage form.

Tie games, a fairly common occurrence in football before the introduction of overtime, were thus somewhat more valuable to teams with a winning record, as compared with current rules.

Note: some team records sum to less than the season schedule (154 or 162 games) due to rain outs.
