I would like to see my K/D for a certain amount of last played maps. To see my current performance.
I am recovering from a bad K/D from my begin game, and would like to see how I am doing right now,but I don't want to reset my stats. This can be applied to other stats also, like W/L ratio or accuracy.
Use the bf3stats.com frame on your statistic overview page at the bottom.
It have a big history over all values.
