02 · Does the hand match?

How Overshoot reads an aim. Evidence you can check.

Every measurement, what it means, and what it cannot tell you. Overshoot points to the moments worth watching. People decide what they see.

The hand and the crosshairhandcrosshair
One kill

From a kill to something a person can check

Every kill goes through the same five steps.

  1. Open the window

    Each kill becomes about four seconds of movement, read from the demo the server recorded.

  2. Line up hand and crosshair

    The raw mouse input is set beside where the crosshair actually turned.

  3. Measure

    Fit, jerk, corrections and more are measured for that one kill.

  4. Compare with ordinary play

    Each number is put in context against real Premier kills made with the same weapon.

  5. A person checks

    Overshoot points to the round and tick. A person opens the demo and decides.

The measurements

Nine ways Overshoot looks at an aim

Each one has its own page. Nothing here is a verdict, and no single measurement decides anything.

01In the app

Mouse-to-crosshair fit

Did the crosshair move because the hand moved it?

Quick explanation

CS2 demos record the raw mouse input next to where the view pointed. Fit asks how much of the crosshair's turning the mouse explains.

Jerk

How abruptly does the aim change how it is speeding up or slowing down?

Quick explanation

Arms and wrists ramp up and ease off. Jerk measures the sharpest sudden change, compared with the flick's own top speed.

Corrective submovements

Humans flick, overshoot or undershoot, then correct.

Quick explanation

After a big flick, a hand usually makes a tiny correction to land on target. Flicks that land dead-on with no correction stand out.

Sequence model

A small neural network reads each window of movement as a whole.

Quick explanation

A research signal trained on labelled matches. It is shown next to the other measurements and never added into the score.

Peak crosshair speed

The fastest the crosshair turned during the kill.

Quick explanation

Compared only with kills made with the same kind of weapon, because a sniper flick is not a rifle tap.

Chance check

How many unusual kills would we expect anyway?

Quick explanation

By definition about 5 in 100 ordinary kills sit in the most extreme 5% of any measurement. The check compares what a player shows with that.

Checkable moments

Every unusual kill comes with the round and tick, so anyone can watch it.

Quick explanation

Overshoot points to the moment. You open the demo there and decide for yourself.

Human verdicts

A person watches the moment and labels it. The label describes the moment, not the player.

Quick explanation

After watching, a reviewer picks one of four labels. Labels are stored without names or IDs and used to check the measurements.

The rules

What Overshoot will never do

  • Label anyone a cheater. It shows measurements and people decide.
  • Show aim scores publicly or rank suspected players.
  • Let kills, K/D or rank count as evidence. Being good is not evidence.
  • Show a number without the tick behind it, so anyone can watch the moment.
