Hi,
As a player, I always wanted to track my skills in a match, but there's a problem: Every match is unique! In one we are fighting against top 100 players, in others is so easy that we don't even need to try hard. So... I tried to create a formula that calculates performance based on your kills, deaths, assits, your match KDR and how balaced the team are. If your team has the highest kills, the result will be smaller, if your team is in disavantage, your score will be higher (because there will be a higher stress on you).
As you can see:
y is the result;
k is your kills;
a is your assits;
t is your team total kills;
o is the opponent team's kills;
For d, t and o: If any of them are 0, then you add a 1, because you can't divide by zero.
I like to call the ration of t and o as "difficulty" and the k and d ratio as... your KDR in the match...
So, my suggestion is a way to track better your progress, better statistics. I don't know if my math is good enough... but there it is if someone wants to use, just give the credits if you are going to share or something...
Oh, by the way: Here is some of my scores...
