Why we don’t show “input lag”
Polling rate is how often the pad reports. Input lag is how long a press takes to reach the game, and a browser can’t see most of that chain: the controller’s own firmware, the radio, the OS, the game, the display. Sites that turn 250 Hz into “4 ms input lag” are quoting the interval, not the lag. What we can measure honestly is how often a fresh report reaches the browser and how even those gaps are, which is what the numbers above show.
