in order to only measure a player's "efficient/effective" APM value. However, there is currently no standardization of what constitutes an "effective action" and APM is therefore typically recorded without any filtering. Accuracy in APM Accuracy is another factor related to a player's APM. Accuracy is the coordination of precise mouse clicks and keystrokes. Greater accuracy will result in fewer mis-clicks and mis-strokes; thus the player's efficiency increases with greater accuracy, meaning the APM is a more accurate measurement statistic.
