When you add up all the kills and divide by all the deaths, the thing that you are averaging is "kills" and you are calculating it on a per-death basis. (Per the analogy dividing total miles driven by total gallons consumed is averaging "miles" on a per-gallon basis). When you add up KD ratio for each player and divide by all players, the thing you are averaging is "KD ratio" and you are averaging on a per-player basis. (Like averaging MPG on a per-car basis.) When you compare an individual player's KD to the first example, there are 2 problems. (1) you are comparing a "K/D ratio" to an average of "kills" (hopefully you can understand that a kills and KD ratios are not the same metrics) and (2) you are comparing a player to per-death statistics (surely you can understand that a player and a death are not the same thing and there is no value in comparing the statistics of the two). When you compare a player's KD ratio to the second example, you are comparing a player's KD against an average KD (comparing like for like) and the comparison you are making is of one player against per-player statistics. If you calculate KD ratio for individual weapons and average those you'd get something else. You'd get per-weapon statistics. It would make sense to compare individual weapons to this average. It would *not* make sense to compare players (KD per player) to this average (KD per weapon). It would also *not* make sense to compare one player's KD ratio with one weapon (KD per weapon per player) to this value (KD per weapon).

I understand that. But if you were to take every players kdr, across all platforms and average that, I still don't see how that could be above 1.0, in any case. For every player that has a high kd there had to be players with kdr that was lowered totaling the same amount his was raised. The deaths have to go somewhere, you don't just raise your kd without effecting someone else's

A number of other posts, including one of mine, have examples. Imagine if one player had every single death. He would have a KD of 0 and everyone else would have an infinite KD. The average KD would be infinite. Really bad players can't get a KD less than 0 and thus are limited in the negative impact they can have on the average. Really good players can have KD much higher than 1. The existence of very good players together skews the average greater than 1. If all deaths are credited to someone as kills, it is impossible for this average to be less than 1.
