"Scoring for CSR will also be dependent on the playlist as some are based on individual performance against other players while the rest is based on team performance and your overall win/loss record.
The following playlists use individual scoring which is based on your performance against other players and your teammates plus your win/loss record.

This is not a “Oh my CSR isn’t 50 this system suxors!!” post, although for all the ranting I’ll do (and all the ranting I wanted to do but cut out) it will seem like it. I will complain a bit and have a frustrated tone throughout, but mostly I’d honestly like to know how the CSR ranking for the SWAT playlist works. You don’t have to read my rant to understand or answer my question, but I’m too upset right now to leave it out and it’s not like it’s the first or last rant ever on waypoint right?

I averaged 20.333 kills and +8.167 K/D in the past six games, always got either 2nd place on the winning team or first place on the losing team, and the system didn’t raise my CSR one iota sticking me at 27 for 5 of the games which I was annoyed with but accepted until the final straw: it actually DROPPED it from 27 to 26 in the most recent game (32 kills +16 in a 3 v 4 game. Naturally I was on the team of 3 and we lost. =_=)
By the way, if I went back to a 7th game (which I won and placed 1st) my averages above would be even higher (the 7th game I got 23 kills and +16 K/D), but I’m counting games from my first loss since CSR came out.I understand that a “win/loss record” of 2/4 (or 3/4 if you count all 7 games) isn’t the greatest, but it seems very disheartening to perform consistently at my best regardless of a win/loss and almost never get a negative K/D…and none of that seems to show at all.
So obviously “individual performance” ranking is either a complete lie, or wins carry much more weight than they should, at least much more so than individual performance. I find it extremely frustrating to start a game minus one teammate against an organized group, get more kills than the first place player on the winning team, get a much higher K/D than the first place player, do absolutely everything I can to win the game…and the system decides “OMG A LOSS, YOU SUCK!!”
I do realize that 7 games is “not a lot” to judge performance on, but my point is even out of “just” 7 games, none of which I quit by the way, I never imagined my performance showed that my rank deserved a downgrade! I’d personally play with someone who averaged 20 kills and +8 per game any day!
I don’t think CSR is even a decent way of determining one’s skill, but I am a very competitive player and team swat is my absolute favorite playlist and I hate to think that despite consistent performance (which I believe others would at the very least call decent right?) that I’d have to place 1st on a winning team 7-8 more times just to freaking get a decent CSR while others who fall into good teams by chance and perform badly just skyrocket to the top. When the skill starts showing up in game (in many months I know, but still) or when people look me up on waypoint at a glance I’m the one who looks like my skill isn’t up to par and that upsets me.

But I digress. When I played Halo 3 I remember being frustrated too, but I wasn’t stuck at a mere 26-27, it was a respectable 41-44, and at least then I could understand why because I was consistently playing in pretty tough games (my very last game of Halo 3 was a team swat game as I just looked it up, I placed 2nd. Ahh memories), but now…I don’t get it. How the hell is it calculating CSR here!?
