I ended up playing with 7 Japanese guys. They did all the work and I just ran around a little. The BTB Slayer scores were:
In one game we were up 16-0. They were amazing to watch; I've never seen anything like that before.
On a side note, if you go to Bungie.com they've updated the gamertag area. Not only do they have past stats but they can show you on a map where all of your kills were and what weapon you were using.
