What is a "kill-to-death ratio"?

A kill-to-death ratio (KDR) is a statistic used in many video games, especially in first-person shooters, to measure a player's performance in terms of combat efficiency. It is calculated by dividing the number of kills a player has made by the number of times they have died in the game. A higher KDR indicates that the player is killing more enemies than they are being defeated, reflecting good performance. For example, a KDR of 2.0 means the player has killed twice as many enemies as they have died. It is often used as a way to compare players' skill levels.
