Tennis betting Q's

Hello guys, trying to start up here betting but you know how that goes. I'm starting small but confused a bit. Could anyone tell me how this asian handicapping works below? Not sure how to read this.

Asian Handicap Tennis

1. Haas vs IIhan
Haas +1.5 sets

2 Fish vs Mello
Fish -5.5 games

 

[Boner_18]

Simply total the sets or games won by each player in the entire match. Subtract/add the spread accordingly and voila.

For example:
Fish wins 6/3, 6/7, 6/3, 7/5

Total fish games - 25
Total mello games - 18
