Understanding PSA Tuning
The PSA method means Perfect Sensitivity Approximation. It is a repeatable way to narrow a starting Valorant sensitivity into a cleaner personal value. The process does not promise a magical number. It gives structure while you test real movement, tracking, bursts, and target switching. That structure helps remove random guessing.
Why It Helps Valorant Players
Valorant rewards calm crosshair placement and controlled micro adjustments. A very high setting may feel fast, yet it can overshoot heads. A very low setting may feel stable, yet it can slow turn speed. PSA testing compares one lower value and one higher value during each round. You choose the value that feels easier to control. The calculator then moves the estimate toward that choice and reduces the range.
Important Inputs
Start with the sensitivity you currently use in Valorant. Add your mouse DPI, because eDPI is sensitivity multiplied by DPI. Use a fifty percent spread for a classic wide first test. Choose fewer rounds for a fast estimate. Choose seven or more rounds for tighter refinement. You can also enter a target cm per 360 if you want the tool to compare a physical movement goal.
Good Testing Practice
Use the same mousepad, posture, and grip through every round. Test in practice range, deathmatch, or an aim routine you already know. Do not change crosshair, resolution, or mouse acceleration during the session. Each change adds noise. Make only one choice per round. Pick lower when control feels cleaner. Pick higher when movement feels more natural.
Reading the Result
The final sensitivity is an approximation, not a command. The eDPI result helps compare speed across DPI settings. The cm per 360 result shows the physical distance needed for a full turn. The next lower and higher values show where another test can continue. Save the CSV or PDF after each session. Review old attempts before making a major change.
Final Advice
Play several matches before deciding. New settings often feel strange at first. Small wrist and arm habits need time to settle. If your aim improves, keep the value. If it feels forced, run another PSA session later with fewer changes. Retest only when comfort changes, not after every missed shot alone.
