The first symptom appears as a high miss rate: you spot a zombie, move into range, and the timer expires. Screens flash “Missed!” while your score stalls, and you feel compelled to repeat the same maneuvers. Behind the frustration lies a mismatched coordinate system—your mental map assumes linear motion, yet the game’s spawn algorithm follows a quadratic decay that your eyes don’t register without a proper graph.
Common advice—press every button, chase visible silhouettes, or rely on trial‑and‑error positioning—misses the underlying cause: the graph’s axis scaling is wrong. When players use default grid sizes, the decay curve compresses, hiding the sweet spot where zombie velocity intersects capture range. Consequently, even seasoned players “feel” they are improving, while the data never aligns, leading to endless loops of ineffective attempts.
