Q: What is the PSA Method for finding mouse sensitivity?

The PSA (Perfect Sensitivity Approximation) method is a systematic mathematical routine used by esports aim coaches and pro players to find a player's optimal individual mouse sensitivity. It tests extreme high and low bounds relative to a baseline, narrowing the difference across 5 to 7 iterative rounds until converging on the exact perfect sensitivity.

Q: How do I test each sensitivity round during the PSA method?

Load into your game's Practice Range (e.g. Valorant Range, CS2 Aim Botz, Apex Firing Range). Pick a target or head dummy, walk left and right while keeping your crosshair glued to the target's head (smooth tracking), and perform 180-degree quick turns. If your crosshair lags behind your movement, you need higher sensitivity; if your crosshair overshoots or jitters, you need lower sensitivity.

Q: How many rounds does the PSA method take?

The PSA method typically takes 6 iteration rounds, requiring approximately 5 to 10 minutes of active in-game or in-browser testing to converge within 0.005 precision of your optimal sensitivity.

Q: Should I use the PSA method for Valorant or CS2?

Yes! The PSA method is ideal for tactical shooters like Valorant and CS2 where micro-adjustment precision and headshot alignment are paramount. It ensures your sensitivity matches your natural hand anatomy and mousepad friction.

Q: Can I convert my PSA Perfect Sensitivity to other games?

Yes! Once the calculator finds your perfect sensitivity in your primary game, our built-in export matrix translates the exact 1:1 physical distance (cm/360) to all other games including CS2, Apex Legends, Fortnite, Marvel Rivals, Deadlock, and Call of Duty.

How the PSA (Perfect Sensitivity Approximation) Method Works

The PSA method mathematically bisects your aiming spectrum. Start by entering your comfortable current sensitivity. The calculator will generate a Lower Sens (Base × 0.5) and a Higher Sens (Base × 1.5).

In each round, test both values in your game (or practice on the tracking target below) and choose which one feels more natural and stable. Through 6 iterations, the algorithm converges on your exact Perfect Sensitivity.

Optimal Aiming Science

Find Your True Perfect Sensitivity with the PSA Method

Copying pro player settings like TenZ or s1mple only gets you halfway. Every gamer has unique hand biomechanics, grip styles (palm, claw, fingertip), mouse weights, and mousepad friction. The PSA method (Perfect Sensitivity Approximation) is the industry-standard algorithm used by aim coaches to discover your personalized, mathematically optimal sensitivity.

Our interactive perfect sensitivity calculator and sensitivity finder guides you through 6 comparison iterations. By comparing higher and lower boundaries and tracking stationary targets, the calculator eliminates guesswork and pinpoints your highest accuracy zone for Valorant, CS2, Apex Legends, Marvel Rivals, Deadlock, and Fortnite.

Testing Methodology

How to Perform the PSA Sensitivity Test in 3 Simple Steps

1. Enter Baseline & DPI

Input your hardware Mouse DPI (e.g. 800 DPI) and your current approximate in-game sensitivity (e.g. 0.5 in Valorant or 1.5 in CS2). The tool generates initial lower (Base × 0.5) and higher (Base × 1.5) testing bounds.

2. Test Tracking & Flicking

Apply Option A in-game for 45 seconds. Walk and strafe left/right while keeping your crosshair locked onto a stationary bot's head. Next, apply Option B for 45 seconds. Select which option felt smoother and required less straining.

3. Converge & Export

Repeat through 6 rapid rounds. The algorithm calculates the geometric midpoint at each iteration. Upon completion, copy your final Perfect Sensitivity and export it 1:1 across all your favorite games.

Diagnostic Checklist

How to Tell If Your Sensitivity Is Too High or Too Low

Signs Your Sens is Too High:Overshooting

Crosshair shakes or jitters during smooth tracking.
You frequently flick past enemy heads and have to pull your crosshair backward.
Micro-adjustments at long range feel uncontrollable or twitchy.
Wrist feels tense or fatigued after short deathmatch sessions.

Signs Your Sens is Too Low:Undershooting

Crosshair consistently lags behind fast-moving enemies.
Performing a 180° turn requires lifting your mouse 2 or more times.
You run out of physical mousepad space during intense firefights.
Shoulder or forearm feels exhausted after clearing tight corners.
