By analogy to cricket batting averages, the points for winning an ODI match are always greater than the team's rating, increasing the rating, and the points for losing an ODI match are always less than the rating, reducing the rating. A drawn match between higher and lower rated teams will benefit the lower-rated team at the expense of the higher-rated team. An "average" team that wins as often as it loses while playing a mix of stronger and weaker teams should have a rating of 100.
