Frag Display Formats

There are three different formats to display kills/deaths

Minimal

Displays only aggregated by category

===== Your kills =====
PVP: -1
Aggressive mobs: 5
Neutral mobs: 2
Friendly mobs: 0

Mobs are considered friendly, if they never attack the player even when provoked. Neutral mobs will turn hostile when attacked first. While aggressive mobs actively attack players.

A negative number means, you have been killed more often by this category of opponents than you killed them.

Full

Displays only categories but kills and deaths separately

===== Your kills =====
PVP: 0/1
Aggressive mobs: 7/2
Neutral mobs: 3/1
Friendly mobs: 0/0

Detailed

Shows every mob separately, distinguishes between kills and deaths

===== Your kills =====
PVP: 0/1
CREEPER: 5/1
SKELETON: 1/1
ZOMBIE: 1/0
WOLF: 3/1

All three examples show exactly the same situation. The player has been killed once by a creeper, a skeleton and a wolf. The player also lost a battle against another player. The player never killed any sheep, cows, etc., but three wolves which are considered neutral.
