Few people know that each weapon in Counter-Strike has several “spray patterns”; A formation of bullets formed while standing still and spraying through an entire clip of ammo.
A few points about these “spray patterns” are:
Patterns are only predictable while not moving, once you move they become to random too predict. While crouching, the patterns seem to crunch together, forming a tighter, more accurate pattern. Each weapon has approximately 3-4 different spray patterns. By just looking at your gun model, and the way your screen corrects, it is “sometimes” possible to predict which “spray pattern” your gun recoil is projecting.
