Field notes
The calibration flow asks the user to choose a physical swipe length, move the mouse across an on-screen ruler, and derive DPI from the resulting movement counts. Other panels expose event frequency, timestamp jitter, velocity, and nominal-stage deviation, while separate calculators cover eDPI and cm/360 values for games including CS2 and Valorant. The page also offers Copy Log and JSON controls for its telemetry.
