What an Elo rating tells you
Two players with equal ratings should stand an equal change of winning A player with a rating 100 points higher should win 64% of the time. A player with a rating 200 points higher should win 76% of the time.
This application uses a K factor of 50. Therefore 50 is the most points a player can win or lose in a single game. When the players have an equal rating the winner will gain 25 points and the loser will lose 25 points. If a higher rated person beats a lower rated person they will gain fewer points then if they beat a higher rated person. The lower rated person who loses to higher rated person will also lose fewer points then if they lose to a higher rated player.
