Assuming you have gotten your 500 overall kills and 100 sniper kills while boosting Team Veteran (where it is much faster to boost kills than in a solo match), the following settings should let you crank through solo games about as quickly and easily as possible:
Victory: 5 points
Zone: 1 Central
Game Start Timer: Off
Auto Launch Timer: 30 seconds
When the round starts the person winning runs toward the green symbol on the screen until he or she enters the circle and the timer starts. Five seconds later the match is over. Only the person winning has to move, allowing the other boosters to wander off for a few minutes until it is their turn. When we did it, matches were taking 16-24 seconds per match, not including load times, so boosting all 10 wins should take 10 minutes per person, tops.
Good luck to you and happy boosting.
