Frequently Asked Questions (PSA Method Calculator & Perfect Sensitivity A/B Testing Tool)
10-Item Technical FAQ & PointerEvent Telemetry Troubleshooting
What is the PSA (Perfect Sensitivity Adjustment) Method?
The PSA method is an iterative mathematical A/B testing framework developed by esports aim coaches to discover a player's natural muscle memory sensitivity.
How does the 7-round PSA method test work?
Starting from a base 360-degree turn, you alternate between Higher and Lower sensitivity multipliers in 7 rounds until converging on your perfect sensitivity.
Why is the PSA method superior to guessing sensitivity?
PSA relies on empirical tracking comfort rather than random preference, systematically narrowing down optimal physical control.
How long does a full PSA method test take?
A complete 7-round PSA evaluation takes approximately 10 to 15 minutes of in-game tracking practice.
What tracking exercises should I perform during PSA rounds?
Strafe back and forth while keeping your crosshair locked on a static bot or target pillar.
Should I perform the PSA method in-game or on a web canvas?
Perform tracking movements in your primary game or our interactive target tracking canvas.
What if both High and Low options feel uncomfortable in a round?
Choose the option that causes fewer crosshair overshoots or erratic micro-corrections.
How often should I recalculate my sensitivity with the PSA method?
Recalculate PSA sensitivity when changing mouse weight, mousepad surface, or physical desk ergonomics.
Does the PSA method work for all FPS games?
Yes, PSA outputs a final target sensitivity adaptable to CS2, Valorant, Apex Legends, and Overwatch.
