Halo 3 50 in team doubles?

[electronicallycrippled]

Im a 40 in doubles with like 36 exp., and my friend is a 36 with like 70 exp., how long would it take me to get my 50 with him, his account is only bad because it was his first, this is my second
we are really good together, how many games would it take to get to a 50, say.. this weekend when ill have a lot of time to work on it?
