WPM = correctly matched characters remaining in your input ÷ 5 ÷ elapsed minutes. Raw WPM counts all characters remaining in the input. Accuracy measures correct character attempts ÷ all character attempts, so backspacing does not erase a mistake from accuracy. Consistency measures how stable your sampled WPM was (100 − coefficient of variation, clamped to 0–100). Results from different modes and durations are not directly comparable.
