Tennis is NOT about winning more points, but about winning IMPORTANT points. You can have something like 76 06 76 06 64 - winning EIGHT GAMES LESS than your opponent - and still win the match.
Hell, Hernych/Gicquel is a REAL example of somethign like this.
Hernych wins 0-6, 6-4, 6-4, 6-4.
Games: Hernych 18, Gicquel 18
