For the absurd values I have added an additional check and proposed it to Paul.
That's due to ET's weird behavior during warmup periods.

Grenade kills and launchergrenade kills are not counted for this display.

This is because they are not rated separately in the new rating method, they are inside the engineering xp and we don't want to double award those kills.

If that is no explanation for your problem Papii then you will need to explain it again because I don't understand it completely
