Losing elo for wins (all the time)

I'm aware that the approach with measuring individual player performance does not work very well for CTF. The formula I use to calculate a performance is derived from what the folks in #ctfpickup used in EU. I even capped the weight of the damage factor ... but there is still a very strong damage component in that formula.

Long story short, I can't (and don't want to) use match win/loss for a number of reasons, which I explained in the Q&A. So I can only try to make the best out of situation and use whatever data the game gives me to come up with some metric which correlates with expected match outcomes.
