I find that my way is faster no offense IKevIKev, it works similar to your way and less work is required especially if you do it by yourself with an extra xbox and copy of the game.
Host a custom Player Match, Death Match on Fate's Dam max players 2, private 2, time limit 5, score limit 20 map cycle off. Now the person going for the match wins grabs the grenade launcher faces the nearby door (note stand behind the grenade launcher spawn) and shoot through the door into the far back corner where your boosting buddy should be standing. He will die and continuously spawn back exactly where he died allowing you to reach the score limit of 20 within roughly 40 seconds if done correctly.
Not only will you get a match win but you will also get anywhere from 9-12kills a match making your boosting that much more efficient.
Also if your boosting buddy has a SFIV turbo controller he can just tape down the RT (spawn button) so he will instantly keep spawning allowing him the freedom to go do other activities such as sleeping while the other guy can boost match wins for as long as he likes since the matches will keep starting automatically in player matches.
I recieved my 10,000 kills at about 850 match wins. So you'll just have to grind out that last 150 wins which isn't bad, opposed to getting all 10,000kills then boosting your 1000 match wins.
Also this works for getting a double, triple, and quadruple kill with just 2 people.
