You're not inconsistent. Your mistakes are.
⌨️
"You shoot 48ms too early"
CS2 bullets spread wildly while moving. We measure your exact counter-strafe timing and show how many kills it costs you.
🎯
"Crosshair 3.4° too low"
AK headshot = instant kill. Body shot = 27 damage × 4. We track your pre-aim on every shot.
🖱️
"67% of flicks overshoot"
Your sensitivity is too high for your muscle memory. We calculate the exact adjustment.
These are real numbers from real analyses. Yours will be different — and specific to you.

What we measure — and how confident we are
Every metric is classified by data source. Nothing is made up.
Directly measured
Accuracy, HS rate, counter-strafe timing, pre-aim angle, return-shot latency, weapon stats
Parsed tick-by-tick from your .dem file
Calculated from measured data
Aim Grade, sensitivity correction, first-bullet accuracy, burst/spray control, shot discipline
Formulas applied to measured inputs — see methodology
Heuristic / Experimental
Aim path analysis, spray transfers, pressure performance, fight context, clutch estimates
Marked with badges — not part of Aim Grade
Pro benchmarks
Computed from real pro match demos, analyzed through the same pipeline. Shown with sample size (n=).
Confidence / reliability
Every analysis shows a sample reliability score. Low shot counts get a visible warning — we don't hide uncertainty.
