1. Start with your real sensitivity
Use a comfortable setting you already know. The first pair is half and one-and-a-half times your base value, giving you a broad initial comparison.
Find your comfortable
FPS sensitivity.
Use the PSA Method to compare lower and higher settings in your own game. Seven deliberate choices narrow the range — the calculation is exact, while the recommendation comes from your real in-game testing.

How the PSA Method works
Seven rounds of controlled comparisons, using the actual sensitivity value from your game.
2. Compare Lower and Higher
Apply both candidate values in your game. Keep the practice drill and setup fixed, then choose whichever makes repeatable corrections easier.
3. Narrow the next round
The calculator averages the current base with your chosen candidate. Later-round factors move closer to 1×, so the tested values become smaller adjustments.
A repeatable test beats random tweaking
Use the same conditions so you're comparing sensitivity rather than several variables at once.
Recommended practice routine
- Warm up briefly before starting the test.
- Choose a repeatable drill that includes both small corrections and larger turns.
- Spend roughly 30–90 seconds on each candidate as a practical starting point; repeat if neither feels clearly better.
- Alternate which candidate you try first to reduce order bias.
- Do not change DPI, FOV, resolution, weapon, scope mode or mouse settings between candidates.
- After round seven, use the output for several practice sessions before deciding to keep or adjust it.
What PSA can and cannot tell you
It does: calculate candidate numbers from the base, round factors and your recorded choices, preserve test progress in this browser, and show a transparent round-by-round history.
It does not: measure aim accuracy automatically, know which candidate you tested correctly, prove that a setting is objectively optimal, or promise that your scores will improve.
The game picker is a note-taking aid only. PSA works on the in-game sensitivity scale you enter; it is not a cross-game sensitivity converter. Start a separate test for each game's own sensitivity value.
PSA Method Calculator FAQ
Answers to common questions about using the tool and interpreting the final value.
What does PSA stand for?
PSA stands for Perfect Sensitivity Approximation. It is a guided way to compare lower and higher sensitivities and narrow toward the setting you prefer in-game.
Is the result guaranteed to be my perfect sensitivity?
No. The result is calculated precisely from the choices you enter, but those choices are subjective. It does not measure aim performance or guarantee better accuracy.
Why are there seven rounds?
This calculator uses a documented seven-round factor schedule, beginning with a wide range and ending with a smaller adjustment around the current base. Each choice updates the next base.
Should DPI or FOV change during PSA?
No. Keep DPI, FOV and other settings constant during a test. PSA changes the in-game sensitivity candidates; changing several variables at once makes comparisons less useful.
Can I use the PSA tool for any FPS?
You can use the preference-search process in games where you can enter a usable sensitivity value. Keep the game and aiming mode consistent throughout the seven rounds.
Does the calculator save my progress?
Yes, when browser storage is available, your current test is saved locally in this browser. It is not sent to a SensConverter account or server. Use Reset test to clear it.
Algorithm reference: the seven-round PSA workflow and candidate averaging approach are described in public PSA calculator guidance. See PSA Method Calculator and its step-by-step tutorial. SensConverter's calculator performs its own client-side calculations; your selection is the deciding input.
