Herlock Sholmes: "2 out of 3" would be simply a "2 win match", 4 out of 7 would be "4 win match" they are the same just not called the same as to what you are accustomed to.
As far as the 10 game match, it shouldn't be confusing, it is simply a "10 GAME match", you either win by wining more than 5 games, lose by losing more than 5 games or tie by winning 5 games, if it were the way you suggested it would have to be called a "most points in x games match"
