1. The Mathematics of Typing Mistakes
A single mistyped character requires: (1) cognitive recognition of the error, (2) moving your pinky to hit Backspace, (3) re-aligning your hand back to home row, and (4) typing the correct key. This costs an average of 0.8 to 1.4 seconds per error.
At 80 WPM, making just 3 errors per minute cuts your effective Net WPM down to 65 WPM. Flawless accuracy is the fastest route to high speed.
2. Tactile Anchor Bumps (F and J)
The small raised ridges on the F and J keys allow your index fingers to locate home row entirely by touch. Whenever your hands wander or make a mistake, do not look down at the keyboard; feel for the bumps to reset your position.
3. Metronome Cadence & Steady Rhythm
Erratic typing—speeding up on easy words and crashing on hard words—destroys consistency. Practice typing at a constant, unhurried pulse. Once your accuracy stabilizes at 99%, gradually increase the baseline tempo.

One common cause of errors is using the wrong finger for a key (e.g., reaching with the index finger to hit C instead of the middle finger). Never compromise finger assignment for temporary convenience.
