COMMENTS

Tie-break games are played to 7 points in all sets except the last of the match, which is a 10-point tie-break.

The structure of sets and games in tennis means a player can win more points but lose the match.

The highest win/loss ratio for 5 sets occurs with game scores 6-0 6-0 6-7 6-7 6-7, where player A wins games by points score 4-0, and loses by 2-4 in ordinary games and 5-7 5-7 8-10 in the three tie-break games.

Player A wins 174 points and player B wins 96 points, but player A loses the match.

This ratio is a little lower than when the final tie-break is played to 7 points (see A368008).
