First off, thanks for the information. It's working great. I did thorough testing and can confirm the following:
1) If you die under 1 minute you get 0 renown
2) If you score edit to 5000 you'll get maximum renown
3) You can suicide, as long as it's over 1 minute into the game
I kept playing until I got a hostage rescue map so it has a timer at the top (I was using my cell phone stopwatch before). Then I'd score edit to 5000 and wait until 1:01 and frag myself. Works for 450 renown every single time (with the boost). This also means it can be automated using the other guy's method in the post
