Corrective submovements

After a big flick a hand usually overshoots or undershoots, then makes a tiny correction. Flicks that land dead-on with no correction are unusual.

Did the flick land with the small correction a hand usually makes?

Distance from targetIllustration, not real data

Distance from target falls quickly, then a small bump as the hand corrects.
Flick, then a small correctionThe hand lands close, then fine-tunes.
Distance from target drops to zero in a single step.
Lands dead-on, no correctionDistance drops to zero in one step.

What it is

Psychologist Paul Fitts described in 1954 how human aiming trades speed for precision. A hand covers most of the distance quickly, then finishes with one or more small adjustments. Overshoot looks at how a big flick ends and whether those small adjustments are there.

Why it matters

It is the strongest single signal Overshoot currently measures. Aim software does not have to follow the hand's rhythm, so landing exactly on target every time, with no finishing adjustment, is unusual.

What ordinary play looks like

Plenty of honest flicks land without a visible correction, especially short ones or ones against a large target. The measured rates, and how often honest players trip each check, are on the How it works page.

How Overshoot shows it

The report card shows it as a caution level, never a verdict, next to the other measurements for the same kills.

Keep in mind

What this cannot tell you

  • Short flicks and big targets often land without a correction in honest play.
  • It works on big flicks only, so it needs enough of them.
  • A missing correction is a reason to watch the moment, not a conclusion.
