## Editorial & Measurement Policy

DpiChecker operates an independent hardware testing laboratory utilizing high-speed optical capture rigs and sub-millisecond USB telemetry sniffers. All measurements are executed entirely client-side using the HTML5 Pointer Lock API and raw PointerEvent coalesced streams with zero OS curve acceleration and zero third-party telemetry.
