[quote] Easy way to look at it, is with small numbers: 2 players playing a match. Player A goes 1 and 2. (.5kd) Player B goes 2 and 1. (2.0kd) Yes the total deaths to kills is 1.0, however the average kd (2.5÷2) is 1.25 The same would be true on a global scale. Adding up total kills and dividing total deaths minus suicides, is about 1.0 but it's not truly relevant on any level... [/quote] This is incorrect. Averaging rates doesn't work that way. You can't do a straight average on rates and get a number that's going to tell you anything meaningful, because you're giving the same weight to every variable. The OP has it right, the formula for calculating average combat KD is sum of all kills / (sum of all deaths - suicides). If you do a straight average rather than using a weighted average then you're saying that a player who goes 1:2 (0.5 K/D), impacts the global average K/D as significantly as a player who goes 24:3 (8.0 K/D). Because the second player has far more data points (kills and deaths), they impact the overall average more significantly with only a few data points.
